It occurred to me after the discussion yesterday, that the Mastodon Organization may not legally be able to call for a block here, as that may be considered anti-competitive practices. If that's the case, then the smartest thing they can do is keep their mouths shut, reaffirm that this is an open network, and wait for Threads to Federate and wait until they have shown, in such a way that can be proven in a court of law, that they are completely unable to moderate content which is illegal in Deutschland, where the Mastodon Organization is based.
Regardless of why they are doing it, whether or not a server blocks other servers does not affect other servers that don't block them. Blocking a server over the lack of a block is absurd, and a quick way to degrade the connectivity of the network: all admins would be doing is cutting their users off from the largest good-faith server.
There are good reasons to Limit posts from .Social, this isn't one.
