Wow, didn't know the people making Lemmy were that bad and deny genocides. But I also don't have time to read and understand all the old posts, and I have no idea who the people are who are talking abotu this, so it is incredibly hard to say if it is trustworthy or not. Would be interesting to get a statement from the lemmy developers today about this, to see what they think about the uighur thing and north korea today.
Where's the actual questionable content? All I could find was a Mastodon thread claiming the devs have shitty opinions without any links to any actual people raising these opinions. The best I can do is guess they are referring to lemmygrad, which indeed looks like a brain dead shit hole of insanity, but how does that relate to the developers again? A bit more clear-cut presentation would be greatly beneficial, as this level of discussion is FUD as best.
Ditto, I see people everywhere but not actual evidence from the developers. Best I could find was some questionable essays in the main dev's Github, but so what? If I buy clothes through Shein now I am some child labor apologist? If we keep rejecting people with good ideas for having shitty opinions we will die waiting.

Link to the said essays, so it's clear what we're dealing with here: https://github.com/dessalines/essays

Ok, so the guy likes his communism. I do find it weird (and a bit stupid), but he can't control the instances he hasn't started, and doesn't directly benefit from them. So it's very hard to see the problem here.

Yeah, I think people may be overreacting a bit, the whole point of federated social media (and FOSS software), is that nobody really owns anything. This is not like if the CEO of some company did shady business or something, personally I couldn't care less.
My concern is that he will use his admin powers in relevant subs ([email protected]) to suppress relevant topics there. I don’t think that requires forking in itself, but might justify defederation to help alternative groups grow.
