Europe is adopting open source and open protocols, not to promote individual sovereignty, but explicitly to protect European sovereignty from foreign influence. This is not what these technologies were built for; "promoting democracy" does not protect the rights of individuals.
The technology listed is mostly federated, not radically open (like, for example, nostr). In particular, ATProto has provided the EU with the perfect opportunity to signal openness while simultaneously standing up a new walled garden in which dystopian "moderation policies" will be the norm.
