The main thing the fediverse offered is a way to avoid any single admin from taking over the whole thing. One instance gets too dictatory, users can move to another instance and still have at least some of what they left behind. And because of that, it will limit the amount of money that capitalists are willing to spend on it because their purchase itself would turn the asset toxic.

But it's otherwise still people running, moderating, participating, lurking, and automating here, and they cover the whole spectrum.

Idk, the moderation distribution helps, I think. I agree that it will become a problem for very large fedi servers, but that's just an argument for increasing the number of small and medium servers

sorry but i dont think so because since so does corporate social media has its own moderation issues
