I would not sing up for Meta run instance, but it is because I don't really trust it will last. In a big corporate scheme of things, it is an experiment and can be killed anytime because it is really nobodys passion project to maintain. So I really doubt a Meta run instance will be better than a multitude of community run instances in the long run.
But yeah, I'd sway for defederate. Meta is a corporation and it's intentions are what they are. It's not "fair" but also its not like Meta is comparable to another community in the fediverse.
Same. With wefwef "back" works as expected.
