This article addresses the need to find alternative ways to envision, develop and govern public service media’s (PSM) online services and data-driven systems. By critically discussing both opportunities and shortcomings of how European PSM organisations developed their online services and personalisation systems, we argue that in their own platformisation processes, PSM have partially lost their distinctiveness and have not been able to provide viable alternatives to the dominant audiovisual media platforms. Thus, building on Mouffe’s agonistic theory and Illich’s conviviality theory, this article proposes a theoretical framework to radically rethink the guiding principles and rationales driving public service platforms, in order to develop viable alternatives to the currently dominant models. By doing so, we envision the development of such services as convivial tools that are based on three principles, namely, symmetry of power (intended as hackability, openness and algorithmic conviviality), independence and environmental sustainability
