That’s not why sh.itjust.works was defederated from Beehaw. It was defederated for having open signups resulting in moderation issues and botting. This thread is an affirmation that it was a good call since they now have toxic users creating toxic communities which is part of the reason for defederation.
You’re creating a problem that doesn’t exist to get mad at it.
Most ot the users here still have Facebook/Instagram accounts they use daily. They like to talk up the fediverse but also post minion memes to their grandma. It’s kinda sad, but it is what it is, and that’s why you see so many Meta defenders.
