Often admins of the "good side" of the fediverse refer to instances they blocked as "alt fedi" or "dark fedi".
Fedi was originally built so that users can block and decide themself what they want to see, very anti authoritarian.
However in the last years the behavior shifted from admins taking only the most necessary actions to keep the peace to controlling servers very hard and even try to get other instances to defederate instances they personally do block.

So my post is criticism of exactly such admins.

Of course the whole topic is much more complex, dont get me wrong, i do think that there should be some safer spaces so that everyone can feel comfy.
However if you became familiar with the technical depths of fedi, then you will realize that fedi is a privacy nightmare, extremely unstable and is based on principle which do makes safer spaces nearly impossible.

And since some people want the network to change actively, the fediverse now have a bunch of admins which started to propagate values like intransparency and authoritarian structures. To give you a bunch examples:
shared blocklists, so that admins can be lazy and dont do their job and which often contains false positives or other admins would categorize stuff different and nearly all blocklists dont have receips for the blocks, someone even tried to capitalize shared blocklists. Another thing is contact depth or personal issues between admins of which the users are then the sufferers, there are several incidents where attempts have been made to actively marginalize minorities.
