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”.
People are concerned because there were examples of such things going horribly wrong, most notably with Google and XMPP.
Way back in the day, Google announced that its Talk messenger will support XMPP, which made decentralization fans very happy - finally, they can communicate with everyone from the comfort of their decentralized instance!..oh.
Google started implementing features in Talk that are incompatible with XMPP, and then dropped XMPP support altogether, ending up deprecating Talk in favor of Google-only Hangouts. This forced many XMPP users to get into Google’s ecosystem, since the people they contacted through XMPP were mostly just using Google Talk, and they couldn’t be contacted through XMPP any more. As a result, XMPP became worse off than it started and got practically forgotten by all but 1,5 nerds who keep it alive.
now most of their contacts were in defederated Google to which they now didn’t have access.
