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.
Assumption 1: Meta / Mark Z are objectively untrustworthy
Assumption 2: The Fediverse is a threat to the entire internet advertising machine
Assumption 3: Threads will be a hospitable place for right wing hatemongers. Therefore, federating with it exposes our most vulnerable users and communities to a deluge of (often invisible) hate and harassment.
Assumption 4: Most of the ways that they could use their billions of users and army of programmers to slowly choke us off would go through federation
I think if you believe all four of those assumptions defederation is the clear choice
