This article contributes to ongoing debates on platform regulation by governments and other political authorities (especially the EU as a transnational legislator) and discussions about the shape of online publics. By applying a discourse analytical perspective, key legitimation narratives can be explored. I argue that the EU claims political authority over corporate interests by introducing new legislation to regulate social media platforms with the Digital Services Act. On the one hand, the EU imagines an idealized democratic online public without harmful and illegal content. On the other hand, the new legislation serves the EU’s agenda on digital sovereignty, taking back control from big and US-based enterprises. https://www.cogitatiopress.com/politicsandgovernance/article/view/6735 Share this: Print (Opens in new window) Print Share on Facebook (Opens in new window) Facebook Share on LinkedIn (Opens in new window) LinkedIn Share on Reddit (Opens in new window) Reddit Share on WhatsApp (Opens in new window) WhatsApp Share on Bluesky (Opens in new window) Bluesky Email a link to a friend (Opens in new window) Email Like this:Like Loading...
