MHO… I would not miss Hexbear at all if they were defederated. Most of the content I see from them is pretty obnoxious, and even the “nice, polite” posts have a strong sealion scent to them. I block most of their communities when I encounter them in my All feed, and will probably block the instance once Lemmy has that capability.

That being said, I support the decisions that @sunaurus is making in regard to Hexbear. His decisions about site administration and moderation have always been sensible and competent.
