I've actually just asked that in another post, because I am kind of interested in what people see as Fediverse main idea.
But, thanks for this summary of how Threads looks like, since I'm avoiding it like a plague. You seriously can't even select what content you see? Fuck, that's way worse than I though - that's so obviously a ML model manipulating with people without holding anything back. I hope they've at least done something with the misalingment where it seems to just radicalize people to keep them on the platform, because if not, the world is fucked.
I hate Meta so much...
