The fediverse is not really about avoiding censorship as it is about providing choice. That means the choice to listen to who you want to listen to (i.e. what servers to (de)federate from/to), the choice to post whatever you want (but you might get banned from your own instance or any other instance, that’s their prerogative), the choice of administrators and moderators (i.e. which instance you sign up to and what communities you participate in).
All of that stuff doesn’t really have to do with censorship directly, but it has implications for censorship. The fediverse is not built primarily to avoid censorship though, and in some cases it is made to make “censorship” (moderation) easier, rather than harder.
Yea this has really big astroturfing vibes.
