I’ve seen that some instances have already done it preemptively.
Genuine question here as I’m still new to the fediverse… isn’t defederation a one way street? Like if an instance defederates from Threads, they can no longer see anything from Threads. But Threads can still see things on all the instances? If that’s the case, it doesn’t feel like it’s hurting Meta too much if other instances defederate from it.
