As an example, Beehaw just de-federated from lemmy.world and from sh.itjust.works. But since I primarily drop anchor at startrek.website (and since I've replicated my subscriptions across all my accounts), I just flip over to that account and still have access to everything.
Expected reasons. Federated systems make moderation more difficult, compounded with poor availability of moderation tools on the platform today. https://beehaw.org/post/567170
Damn most of my communities were from beehaw. I didn't join the instance to spare the server load, but now I think I might join it directly since I don't want to make another account on a different instance that may get defederated later on down the line.
