It should come as no surprise that the lemmy.ml admin team took about 2 minutes to decide to pre-emptively block threats / Meta. Their transparent and opportunistic scheme to commodify the fediverse and it’s users will not be allowed to proceed.
We strongly encourage other instance administrators to do the same, given the grave threat they pose to the fediverse.
The admins of lemmy.world are generally opposed to defederating and have apparently announced via mastodon (i haven’t seen the official post but several comments have said) that they will wait and see what threads federation looks like before deciding whether or not to defederate.
