Maybe it should be a common practice to list larger servers that you've chosen to defederate from? Beehaw is being forthcoming about it, so at least people know what they're missing out on. And I don't think they'd have a bunch more hidden away from us. Now, if a community does this and tells no-one, that could be a genuine problem. Making an account on another instance is a little annoying, but it's not that bad if you're old and accustomed to classical forums.
Edit: I didn't even notice the /instances URL on Lemmy. GG, it's already openly out there.
I don't like Elon as much as the next person, but I dislike the music industry cronies even more. Yeah, I'd agree this is bad.
