One thing I don't see discussed in this is that .art is full of artists. A lot of freelance artists suffered greatly when Elon torched Twitter. And the fediverse told them, come here, you'll be safe, we'll take care of you. And they came and rebuilt the audiences they need to survive
So if an admin of a large instance defederates in the heat of the moment it's not just a bit of social graph people lose. Some artists almost certainly took a real, quantifiable financial hit out of this. After they were told the fediverse was safe. How is this a remotely acceptable outcome?
