The EU Commission updated its official website to replace its X (formerly Twitter) follow button with a Mastodon link, reflecting the institution's shift away from Elon Musk's platform toward open social networks. This move aligns with the EU's broader regulatory push for platform interoperability and data portability — documented in recent AI Act and Digital Services Act enforcement. The change is symbolic but meaningful: major institutions moving off centralized platforms signals accelerating adoption of federated social networks in Europe, which could pressure other tech platforms toward similar interoperability standards.
