Meta just announced that they are trying to integrate Threads with ActivityPub (Mastodon, Lemmy, etc.). We need to defederate them if we want to avoid them pushing their crap into fediverse.
If you’re a server admin, please defederate Meta’s domain “threads.net”
If you don’t run your own server, please ask your server admin to defederate “threads.net”.
So let people register and use Fediverse. Meta may provide some new cool thing which will talk via ActivityPub, and people may install and host it. That’s the acceptable way for their contribution.
Attaching a whole platform controlled by them centrally - no.
