Il design delle piattaforme social tra rischio psichico, modello economico e vulnerabilità. Riflessioni a partire da K.G.M. v. Meta et al. 

This paper examines K.G.M. v. Meta Platforms, Inc. and YouTube LLC as a point of emergence of a conceptual transformation in the liability of social media platforms. The psychological risk associated with social networks is not traced solely to exposure to harmful content or to pathological patterns of use, but rather to the technical-economic configuration of digital environments: that is, to the ways in which platform companies translate logics of valorization into design choices, optimization metrics, and structural conditions of interaction. Through a comparison with Section 230 of U.S. law and with the literature on algorithmic design, digital manipulation, and vulnerability, the article shows how platform architecture may be understood as an ordinary condition for the production of psychological risk. From this perspective, K.G.M. makes it possible to interrogate the shift from the attribution of liability for individual pieces of content to the legal assessment of the digital architecture that organizes their visibility, repetition, and salience.
