If you know someone on Bluesky or Threads or somewhere else that tries to connect with fedi (either through direct federation or bridges or whatever) who is confused as to why people on the fediverse get so bent out of shape about said connections and defederate, a legitimate answer you can give them is that some of us have actual standards for moderation.
Those places are terribly moderated, and anyone who gets used to a modicum of good moderation on fedi can tell the difference instantly. So the next time you hear someone complaining about us being isolationist, please remind them of this fact.
