I read an old thread documenting the opinions of Lemmy maintainers
For what it's worth, that thread is openly biased with many of those examples being strawman quotes and misframing events, like a non-sequitur troll post ban being framed as "support for Ukraine". And frankly, some of those points are cm0002 themselves intentionally trolling, like dubiously reporting a political meme as "Propaganda".
Personally I think the main devs are terrible at forum moderation. I'm aware that they're chronically overworked, and that .ml is not intended to be a neutral or liberalist general-purpose instance, and I'm aware that it's very normal for moderators to be bad at moderating, and yet that doesn't detract from my belief that they're technically bad at moderating a forum. For example, simply writing "rule 1" as a ban reason allows people to misinterpret bans as we're seeing here. Automate that shit, prefill ban reasons with the rule list! Make clearer rules and FAQs describing how memes and talking points considered normal in the US are actually chauvinistic propaganda!
As for a fork or rewrite, like others have said, alternatives already exist, but I also don't think this is a case where maintainer opinions are harmful to the user or project (even if I disagree with some). They're devout anticapitalists, which makes their FOSS and anti-enshitification positions clear, I know it won't sell out in five years. They only have power over their own instance, which one is welcome to not join or block.
