TLDR is that the person who removed the community is fairly new to the mod team and didn't realize there was a bit of a history to this situation. Also, looks like they are sticking with the decision this time around though.
Please don't harass the lemmy.world admins/mods though - if you don't like the situation you are free to register here or on another instance. And if you aren't a lemmy.world user, then this doesn't affect you at all.
I'm proud of our community here, and it's their loss, not ours!
The translation is, "It wasn't us don't get angry, but also it kind of was one of us and also we are sticking by the decision so it may as well have been us." I don't really see that it matters if the story is true - in the best possible case they're just saying that they don't have a way of setting policies and having those policies be followed.
If we've learned anything from centralised platforms it's that size doesn't protect platforms from the consequences of making bad decisions.
