I really feel like everyone is letting their emotions and ideologies run the narrative here. Lemmy.world was already defederated with Hexbear, everyone was. What they are doing is choosing to remain defederated once Hexbear federates. And that is perfectly within their rights. Until we get better moderation tools and the ability block instances at the user level I can completely understand why the admin and mods don't want to deal with potential issues. Maybe once we all have better tools then we can try playing nice together. This is the same reasoning Beehaw took and I think it makes sense in this case as well.
