Some examples of reasons stated for blocking individual instances from the Fediverse:
* “libertarianism”
* “TERFism” (feminists that oppose modern trans ideology)
* “Trumpism” (blocking nearly half the American electorate based on their political views?)
* “free speech”
* “federate with evil instances”
Sounds sketchy, right?
At least Twitter 1.0 had concrete guidelines that it could use to justify its censorship.
As can be seen from the list above, Fediblock is highly partisan and arbitrary. An ideal tool for political weaponisation of the Fediverse.
