      <abstract>
        <p>Digital ecosystems and platformisation are emerging phenomena that change our society by integrating technology into our everyday lives. Despite the benefits that technology offers, this tightening bond between technology and humans is problematic as technology has been shown to also bring negative consequences to people's lives. These consequences are acknowledged and in many cases have been taken into account in research and practice. However, we still lack explanations regarding the mechanisms that cause these negative impacts in the first place. In this paper, we present an ontological viewpoint based on Habermas' systemic power/lifeworld model, which offers an expressive framework based on critical theory to reveal the risks inherent in technology. We make visible how technology has a tendency to colonise the Lifeworld of people if not understood at the theoretical level and acted upon properly at the practical level. This will offer a philosophically solid basis and new insights for future research on digital ecosystems and platformisation to endorse human-centric and ethical digital society.</p>

        Digital ecosystems and the platformisation thereof are changing the structures of market economy
[
        <xref ref-type="bibr" rid="ref1">1</xref>
        ], creating new business models [
        <xref ref-type="bibr" rid="ref2 ref3 ref4 ref5">2, 3, 4, 5</xref>
        ], affecting social interaction and changing political and
public values. Digital platforms have a tendency to solidify the position and benefits of central,
orchestrating companies in the field, all while diminishing the opportunities of competitors and
individuals the field [
        <xref ref-type="bibr" rid="ref6">6, 7</xref>
        ]. These changes are all paired with potential unintended consequences and
ethical implications that need to be thoroughly considered. Consequently, there seems to be a strong
need for giving an established role - if not a central focus - to research in ethics when studying
contemporary technologies [8],
      </p>
      <p>Artificial Intelligence in particular has raised ethical concerns regarding emerging technologies,
which has led to creation of a plethora of Al ethics codes and frameworks for governance [9, 10, 11].
Meanwhile, in academia, the discussion around ethical implications of technology can be traced back
to the seminal articles titled "What is computer ethics" by [12] and "Four ethical issues of the
information age" by [13] published almost four decades ago - a point from where ethics has slowly
started to draw attention among technologists. Research has shown that there are problematic issues
that has been brought upon us with and by IT and have risen the demand and implementation of
protecting initiatives, such as legislation [14, 15], ethical codes[ll] and sustainability
frameworks[16].</p>
      <p>Most of the research focusing on IT ethics seems to be analysing the emerging problems and
solutions for those problems, which is undeniably important and needed. However, such approach
does not offer tools for preventing the problems from occurring in the long run, because the focus is
on fixing the symptoms rather than addressing the root causes that make things go wrong in the
first place.</p>
      <p>Therefore, instead of focusing on solving specific problems arising from digital ecosystems and
platformisation, we aim to reveal the ontological foundations of these problems. To do so, we rely on
the work of Jurgen Habermas [17, 18, 19] and more specifically to his idea (critical theory) of dividing
societies into two dimensions, systems and lifeworlds, which are based on different ways of existing
in and affecting the world that are often at odds with each other. Through this perspective to
ontology of the digital ecosystems and platformisation, we hope to contribute to the prevention of
unethical outcomes before they occur. In doing so, we wish to help reveal root causes—in
Habermasian terms, colonisation mechanism build in the systems —for ethical challenges specific for
digital societies, which will hopefully mitigate the risk of falling merely into technological
determinism and overlooking societal aspects of technology. All while recognising that the present
paper is only an initial opening of discussion, we believe this to be a necessary step in order to tackle
specific problems brought forth by the domination of digital platforms and ecosystems by only a few
of actors in the field.</p>
      <p>The paper is structured as follows: In the next section we present our philosophical stance and
research approach based on Habermas’s theory of systems and lifeworlds. In Section 3, we discuss
the application of this theory construction through examples and earlier works around the topic. In
Section 4, we end up with conclusions and potential research topics where the framework would be
particularly fruitful.
2. P h i l o s o p h i c a l stance: L i f e w o r l d and S y s t e m s in H a b e r m a s ’ s c r i t i c a l
t h e o r y
It is reasonable for a reader to question why we have gone all the way back to the philosophical
foundations of knowledge rather than a commonly used empirical research methodology to obtain
information about consequences of digital ecosystems and platformisation. This choice arises from
the very philosophical foundations of research itself. Like Hassan et al. [20] stated: All research is
philosophy in action. Therefore, the philosophical position helps us look at the basis of our
assumptions and to evaluate the research we are conducting [21, 22, 20]. Philosophical approach also
enriches research by offering new insights and viewpoints instead of relying only on more traditional
interpretative research methodologies [23, 24],</p>
      <p>Research always comes with unanswered philosophical questions. Yet, under the academic
publication pressure, word limits and case-specific focuses, they get easily neglected or to taken for
granted, which is why regularly revisiting the philosophical foundations of research is important.
These questions are related to different branches of philosophy, namely metaphysics, epistemology,
rational inquiry and axiology (including ethics), all of which should be considered by a researcher
when conducting research [20]. In the current landscape where information systems (ISs) are ever
more complex [25] and underpinned by scalability, unpredictability, socio-technical dimensions and
low transaction costs, technology is ever more pervasive in our everyday life and thus calls for new,
innovative and holistic theorising and knowledge creation [26]. This is where inspecting the
ontological assumption through philosophy can be of help.</p>
      <p>The position presented herein stems from critical theory. This approach, emphasised by, e.g.,
Mingers et al. [27] and Cukier et al. [28], offers a viewpoint that shifts the focus towards the
underlying causes for problems. Critical research is concerned with questions such as freedom,
autonomy, and human emancipation [29], which often manifests itself as a study of power relations
in society [19, 30, 31, 32], In addition to increasing understanding, critical theories offer a pragmatic
approach to knowledge by aiming at changing society by challenging existing paradigms and
suggesting alternatives [33, 34, 35], This emancipatory and deliberative perspective [30] can be seen
essential for enabling a better world [36]. Thus, the approach presented here is builds on critical
theory and uses the philosophical argumentation for analysis, aiming to give a deeper understanding
and pragmatic, scientifically justified critique to encourage more ethical development and
deployment of ISs.</p>
      <p>We base our approach on Habermas’s model of lifeworld and systems. In his Theory of
Communicative Action Habermas introduces an idea of dividing the society into two dimensions,
systems and lifeworlds, based on their nature of communication and coordination. According to
Habermas [17, 18, 19], a lifeworld is a dimension that is shared by individuals connected to each
other’s lifeworlds. Thus, one’s lifeworld is an arena of communicative construction where they
encounter others, communicate, and observe the world. Systems, in contrast, are based on power
structures that are rooted in systemic integration. For Habermas, these include economic systems,
political systems and administrative systems, where actions serve the institutionalised goals of the
system. Notably, systems are not separated from the lifeworld but part of it. Even though the role of
the system-lifeworld-division is less prevalent in his later works, it remains in the background
throughout Habermas’s discourse theory of society.</p>
      <p>
        This lifeworld/systems model can be used to reveal fundamental issues that underly emerging
problems of digital ecosystems and platformisation, enabling researchers and practitioners to address
them accordingly. Habermas introduces concepts, such as human interaction and rational
communication, that may help us seek a new commonly acceptable way to encounter platformisation
and create ecosystems that are more human-centric [37, 7, 38], Thus, this approach offers a viewpoint
that helps us discover underlying ontological mechanism that are rooted in how technology is
appearing to us and how we are mastering it. This viewpoint is relevant for analysing the past,
current, and future problems of digital ecosystems and platforms as well as the accompanying
services and products, which we will next discuss in more detail through contemporary examples of
platformisation of digital ecosystems.
3. Platformisation as a c c u m u l a t i o n of s y s t e m i c power in digital
e c o s y s t e m s
In an ideal situation, systems are part of the lifeworld in a balanced way, enabling communicative
action and discourse compared to mere strategic action. However, it can occur that systems become
to colonise the lifeworld. In the context of digital platforms, colonisation seems to be connected to
the ever-growing collection and accumulation of data, described as data colonialism, which has
normalised the exploitation of humans trough personal data [39], Van Dijck [40] has visualised this
as a platformisation tree, the roots and branches of which reach all sectors of society while dominated
by the tech giants. [
        <xref ref-type="bibr" rid="ref2">2, 41</xref>
        ], on the other hand, calls this kind of economy surveillance capitalism that
is based on the logic of accumulation, where data is collected from a multitude of sources, then
extracted, analysed, commodified, and finally used to make profit. This form of capitalism based on
data platforms is global in nature and driven by systemic powers beyond reach of individuals and
often also of national governments. For example, the US legislation (Section 230 of the
Communications Decency Act of 1996) protecting the platforms by lifting the liability for unlawful
content serves as a useful illustration of how the systemic power is in part protected by other
institutions [42],
      </p>
      <p>Platforms seem to play an increasing role in data colonisation as a way for companies to move
from data mining to data farming [43, 44, 45, 46]: instead of relying on extracting random big data,
companies build their platforms in a way that yields data that fits their purposes. Correspondingly,
digital platforms can be seen as (often an extremely large-scale) algorithmic simulation that provides
companies with data that best serve making profit.</p>
      <p>This colonisation happens when the platform dominates individuals’ lifeworlds to reach the
system’s needs and thus limits the space of the lifeworld of the people within the system. Hence,
Information Technology (IT) itself can be described as a systemic power as it sets the demands and
significantly affects people’s lives. Our society and governments are largely based on services that
are dependent on IT. Likewise, our everyday life is filled with IT, and most of our digital services are
built upon just a few main platforms (a reason of which those are deemed gatekeepers in the recent
EU legislation).</p>
      <p>This course of development can be subjected to critique for several reasons. Like Couldry and
Mejias [39] have noted, we should resist against building societies based on this kind total
algorithmic control, because it reduces humans into a mere resource for economic purposes. This
does not mean rejection of data collection and use altogether, but instead encourage steering the
current logic of accumulation that drives platformisation and digitalisation towards more humanistic
and ethical direction called for by IS researchers since the earliest developments in computer ethics
[47],</p>
      <p>Another illustrative example of this colonisation by platforms is presented by [48] in their article
introducing a concept of lifeworld economy. Lifeworld economy approach is an attempt to loosely
apply Habermasian arguments and his lifeworld-system model to a different ontological framework.
Elder-Vass provides a novel way of looking at the platform economy by dividing it into lifeworld
economy and system economy. The system economy can be seen as the capitalist economy
performed in the markets, which is commonly seen as the normal economy. However, there are
other kinds of activities (gift economy, feudalism, self-production, etc.) that could be seen as
economies which actually have various overlapping manifestations.</p>
      <p>Elder-Vass [48] sees that dualistic distinction of systemic powers and the lifeworld is not fruitful,
because the two can overlap especially in the context of IT. Elder-Vass uses Amazon as an example:
From the perspective of systemic power, the seller and the buyer are instrumental objects that are
coordinated by systemic rationality. This rationality is based on an algorithmic (therefore, systemic)
process. However, Amazon has also incorporated lifeworld aspects in its services. There is a
possibility to write and read reviews and discuss the products, both of which are communicative
actions that affect the purchases made. However, these review communication channels are
published for strategic reasons even if they create a channel for communicative action. [48] Even
though a clear demarcation of lifeworld as good and systems as bad is tempting, the example of
Amazon demonstrates that reality usually lacks this kind of clear distinctions. In fact, it can be argued
that it is precisely in these grey areas that colonisation of the lifeworld by systems happens, as it
represents how the systemic power expands the area which used to belong to the lifeworld, and this
process happens in the grey area between systems and lifeworlds.</p>
      <p>
        Zuboff [
        <xref ref-type="bibr" rid="ref2">2</xref>
        ], on the other hand, noted that we have not been able to successfully define what big
data is because we have looked at it as technological phenomenon, which prevents us from seeing
its other relevant aspects. However, Zuboff claims that it originates in the social and thus should be
analysed not technologically but from a social perspective. The problem here is that humans are
controlled with technology, which is done out of sight if not specifically revealed [49, 50],
Sinnerbrink [50] offers an acute description on how information technology is unnoticeable,
transforming the actual to become a standing reserve: "The computer is an information interface, the
mobile telephone a “personalized” communication resource on permanent standby; we ourselves
become communication resources permanently “on-call” within social, electronic, and economic
networks". In the grey area, it is indeed the systems that hold power over the course of events with
technology, not the individuals experiencing the lifeworld. Therefore, we argue that the mechanisms
of the phenomena discussed here can be better understood by approaching them through the concept
of lifeworld colonisation.
      </p>
      <p>Thus, even if it would be arguably unfruitful to fully turn our back to technology and neglects its
lost potential, we can change the role it has for us in our lifeworld. We can aim to understand why
technology and other systemic powers are invading the lifeworld. We can analyse the meaning of
technology for ourselves and for our being here. We can refuse to use technology as expected, and
instead search for a way of living that makes sense for us.</p>
      <p>We need to develop and govern IT in a way that respects individuals (lifeworlds) and their
autonomy instead of only feeding economic and corporate powers. Nevertheless, we are bound to
use technology, and most of us are happy—or at least content—with the possibilities it offers us.
Instead of having a negative or a passive stance against digitalisation, we should focus on preventing
the colonisation of our lifeworld by IT. We should seek possibilities to protect the life of individuals—
lifeworlds—so that the outcome of using IT would create positive effects for individuals and mitigate
the negative ones. In the end, these platforms and ecosystems are ever more prevalent, if not
necessary, for many people, and hence are already an integral part our everyday life. Thus, there is
an urgent need to emphasise the role of people and society—as markets on their own will not provide
solutions that serves society [51].
4. C o n c l u s i o n s
In this paper, we have delved into the ontological foundations of information technology to present
an initial theory of a mechanism through which it impacts human lives and societies. We have
presented a critical approach that draws from Habermas’s model of systems and lifeworlds, and
tracks the negative impacts of IT on humans back to the way in which it colonises our lifeworlds as
a form of systemic power. Using platformisation of digital ecosystems as an example, we have
discussed several typologies that target the intersection of systems and lifeworlds and showed that
the ongoing phenomena and perceived issues can be conceptualised using the terminology of
colonisation of lifeworlds by systems. Therefore, we argue that the platformisation of digital
ecosystems and platformisation serve as an illustrative example of manifestations of systemic power
in society that is colonising the lifeworld, driven by technological, economic, administrative, and
political powers implemented trough technology.</p>
      <p>That being so, the present approach offers a viable path towards better understanding of the
mechanisms in which IT affects people and societies. Meanwhile, this is only the first step towards
a solid, philosophically justified framework and thus raises several questions for further research.
However, we believe this to be a useful approach to study, for instance, how the European legislation,
such as the Digital Services Act or the EU Al Act shapes the impacts of IT on people, or how the
recent developments in the ownership of the platform X, formerly Twitter, impacts the power
relations and the public discourse in the digital sphere.</p>
