In this groundbreaking work, Paloma Viejo Otero delves deep into the intricate web of power dynamics and ideological frameworks that underpin platform governance and moderation systems.At its core, the strength of this book lies in its original theoretical approach, which skilfully unpacks the genealogy of platform governance. By tracing the historical roots and ideological underpinnings of these systems, Viejo Otero offers readers a profound understanding of how platforms have come to control and steer online discourse and user behaviour.Platform Governance and Social Justice prises open and questions the power structures and systems of control that platforms have designed and implemented. Through meticulous analysis and incisive critique, the book exposes the often-hidden mechanisms through which platforms shape our digital experiences and influence societal norms.What sets this book apart is its comprehensive examination of the digital platform ecosystem, considering both mainstream and ‘Alt Tech’ platforms. In essence, Platform Governance and Social Justice offers a timely and indispensable contribution to the field. With its rigorous scholarship, nuanced insights, and thought-provoking analysis, it constitutes an original contribution to ongoing debates and will inspire further research in the realms of platform governance and critical digital media studies. Viejo Otero has crafted an important work that not only sheds light on the present state of digital platforms but also offers a roadmap for envisioning more equitable forms of digital governance. The book will be indispensable for both advanced undergraduate and postgraduate students as well as for researchers in platform governance.
