One can quite easily twist "we deny genocide is taking place" into "we don't support genocide." It's easy to say you don't support genocide when you're saying there's no genocide in the first place. Frankly, everything I've read about these guys is repellent and there's no way I'd be donating money to them. I gave money to Ernest, the developer of kbin, instead.

That said, though, this is completely true:

We are individuals with our own opinions. If you disagree with these, it is no problem! You can still freely use the Lemmy software on different instances. If you host your own instance, we have no control over it at all and are unable to censor what users say.

It's an open source program operating with an open protocol and they can't stop the rest of us from using it. If they ever try it'll just get forked. So I see no problem with having Lemmy be a major part of the Fediverse's infrastructure.
