Beehaw is defederating from sh.itjustwor.ks and Lemmy.world.Personally I think it’s silly to be upset over it considering defederation is one of the selling points of Lemmy.
Beehaw is just going for a more curated experience which I think is completely fine. I’m sure once they have more moderators they’ll consider refederating anyway.
I assume for Meta’s platform they’d just get defederated very quickly from others. I think it actually could be a good thing in regards to introducing average users to the fediverse (I say this as someone who despises Meta)
