If the protocol is designed in such a way that it allows the operators of one instance to have full control over what some user identities can access to in the whole network, then it's an issue in the protocol. Imho, the problem is likely inherent to the way the AP fediverse commonly defines "federation".

I'd rather favor a more decentralized structure that allows the users to directly access content from any content provider that hosts it through the protocol (ie. without necessarily requiring another specific instance to index that content from their side.. if they index it great, but if they don't it should still be possible to access it using the same user account from a different index), with a common protocol that allows a separation between identity management and content provider.

From what I understood, ATProto is closer to that concept.
