Lots of instances defederated because of the tendency to brigade. Since Hexbear was already a fairly large instance before federating, it meant it tended to dominate a lot of conversations on other instances. People have similar complaints about .world these days too. But fairly early in the first Reddit exodus, there were a few cases of Hexbear brigading smaller instances, and the Hexbear mods/admins clearly didn’t have any interest in stopping it. So not all of the defederation is purely politically based. Politics may have helped swing the decision, but it certainly wasn’t the only reason.
You got “cynical tween” and “misread Nietzsche” from a four word joke about Arch users? Okay, sure buddy…
