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.
Mastodon.world said they won't pre-emptively defederate (but are prepared to do so as soon as they notice something bad), so I'm guessing lemmy.world has the same stance
