An interesting article I saw (from 2019) describing the potential intrinsic tendency for decentralized platforms to collapse into de facto centralized ones.
Author identifies two extremes, "information dictatorship" and "information anarchy", and the flaws of each, as well as a third option "information democracy" to try and capture the best aspects of decentralization while eschewing the worst.
I appreciate the call for democracy, but I think this totally misses the point of federation with it's complaint that not everybody is going to host their own server. The benefit of federation is not that every individual or small group will run their own server, it's that there will be multiple server options to choose from so if the one you're using goes bad you can just switch to another one. Even just getting to an email like system with a few major players and many smaller ones would be a big improvement over a single centralized server, but what makes Mastodon style federation even better than that is that you can move your account from one server to another in a way you really can't for email.

Not sure how that works. With emails, if I move from email123@aol.com to email123@protonmail.com I lose my old emails and people trying to contact me there, but I can just start over. If I remember peoples’ emails I can also tell them I moved to protonmail and to talk to me there. With federation, if I move servers I lose my comment, post, and upvoted history; people messaging me; and my subscribed communities; but I can just start over. If I remember people’s usernames and subscribed communities I can tell the people I moved and to talk to me there, and re-subscribe on the new account. Unlike with email I can still see my old account’s comments and posts, but otherwise I’m not sure how moving accounts in the Fediverse is different from changing emails.

That is in no way an inherent limitation. It's just a current limitation with Lemmy and kbin.
You can move from one Mastodon instance to another and take your followers and follows with you. And if you move to a Calckey-bases instance, you can even import your old posts.
