Hexbear as a community was never going to leave. We almost lost our domain due to some silly bullshit but thankfully it didn't happen. Even if it had though, we were just looking at a name change, maybe becoming hexbear.ml (or something like that) or possibly rebranding as some other name entirely. But we were never just gonna cease to exist like it appears lemm.ee will.
That said, I am a little sad lemm.ee is going. It may have had its share of asshole users, but there were(are) definitely some cool people on it too. And whatever anyone can say about it negatively, lemm.ee is a hundred times better than fucking .world. My god THAT instance is a cesspit. .World is vehemently, aggressively trying to be reddit 2.0 along with all that implies including amplifying everything that makes reddit a shit website and corrosive lie of "community." Lemm.ee may have had its issues, but if nothing else, it was a solid alternative to .world and that alone is enough to make me sad to see it go. There are even a couple users on it that I hope to see make an account on hexbear and plenty of others that would fit on .ml or one of the the other more generic instances.
Edited to fix typing mistakes.
Seriously, why not just stay on reddit, or (same thing) move to .world? If manually blocking things that are shocking to your precious little sensibilities is too hard for you, there has always been other places that pander to echochamber-seeking dorks like you.
