Also not sure how one can do apologia without believing in what they're saying.
...you can just lie to people... like trolls...
But even if we assume for charitability's sake that apologia ==> believing in the cause, that does not automatically mean that apologia <== believing in the cause. Like they're not being banned for your beliefs. That user was banned for advocating for them. Which again, without context is still an overreach IMO, but this is absolutely not someone being banned for simply having the wrong opinion.
The law can take down the Fediverse
Can they? Sure they can take down individual servers, sure they can make it impossible for money grubbers to make money here make it hard to be profitable, but they can't take us all out.
