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”.
Facebook / meta has too much history of abuse. OTOH I don’t think it’s necessary to fully defederate, but setting a server defaults per-account to filter their instance would reduce their influence and risk of abuse while still allowing people to opt in to connecting to them
