It’s telling they fellt the need to defederate first. They need to controll their narrative, otherwise their views might get challenged and their tankie idiology starts to crumble.
I am for left unity, but tankies always try to strongarm the discussion and don’t really argue on good faith. They don’t respect any idiology other then theirs.
Probably the best outcome, even if it’s a pity losing their more reasonable users.
