It's not shit yet. Right now, it's good. Honestly, better than the fediverse in core usability.
The issue is whether it stays that way. And yeah, if they open up the way you're talking about, I'll probably move over myself, because that's the protection against enshittification. But if they don't open up, if they stay centralised, and just play at federation, then the writing is on the wall for how it ends, because it's happened countless times before. And I won't invest my time or effort in being part of that community only to lose it
If you can find a lemmy trans flag theme that we can easily import, I'm all ears :)
