Well, on the plus side, one of the admins of firefish.social (not the one at the center of this art drama) has been very public about his belief that there need to be lobby servers that do federate with Threads to help provide a path for Threads users to escape the Facebook ecosystem and transition over to the fediverse. He thinks some Threads users will find other servers more appealing in the end. He picked up a second domain, notmeta.social, to eventually set up as a separate fedipact option, but that hasn't even been upgraded from Calckey to Firefish yet so I don't know how seriously they take it.

You won't have access to mastodon.art from firefish.social, but you can access the threads-welcoming side of the fediverse.

Honestly, I was hoping to find a fedipact firefish server that doesn't have meta in the name (why would I want to advertise for them in my server name?), but the information on which servers are in the fedipact is so poorly organized that I gave up on that entirely for now.
