This commentary aims to discuss the article “Ordo-responsibility in the Sharing Economy: A Social Contracts Perspective” from a sympathetic viewpoint toward its implementation of a constitutional contractarian approach to business ethics and due consideration of digital platforms as institutions resulting from a social contract. Nevertheless, the commentary also wants to criticize the article’s interpretation of constitutional contractarian theory and institutional reconstruction of the phenomenon, and thus even the governance structure it is proposed for sharing platforms. The commentary presents another understanding of constitutional contractarianism, referring to both the ex ante agreement and the ex post compliance problem. Moreover, it reframes the history of the evolutionary process of institutions’ selection within the domain of the sharing economy consistently with the idea that the Internet should be framed as a common pool resource. In this way, the commentary suggests an alternative governance structure for sharing platforms, that is, platform cooperatives.
