The idea is a very good one: Federated instead of Centralized, free and open-source software, anyone can run their own instance and federate with all (or some) of the others. Like the old dial-in BBSes of yesteryear before the Internet took off, it’s just a bunch of networked home servers. Sharing among peers, not some big, corporate, centralized proprietary platform. This should have taken off and virtually replaced the big sites like Fakebook, Instagram, and Twitter.
(a) is Centralized, (b) is “decentralized, and (c) is distributed (like the Fediverse)
This is Peer-to-Peer (P2P) stuff that gives people control of their own content instead of making it the property of the service provider. It doesn’t market user information to advertisers and turn it’s users into a commodity to be bought and sold. Examples of platforms like this are diaspora*, friendica, hubzilla, mastodon, pleuroma, funkwhale, writefreely, and more.
This should have exploded all over the place and practically driven the big corporate social media sites out of the market!
But it didn’t, it hasn’t, and it won’t.
Here is why:
As the administrator of my own instance, I might choose to block other instances for whatever reason. I wouldn’t want my users to have access to pornography, for example, or far-left (or far-right) political crap, pro-hate stuff, Nazi stuff, etc. So I might choose to block “diaspora.hitler-was-right.com” (a fictional example) from my own diaspora instance. Hey, it’s my server, I’ll do what I want with it. You want that Nazi shit? Find a Nazi instance and knock yourself out. My server, my rules.
A huge majority of Fediverse servers are run by “left-leaning” administrators, and it has become standard operating procedure for them to block entire instances if even one user expresses an opinion, a data set, a meme, whatever that offends the administrator. The result has become that most Fediverse instances are hostile to my political leanings and religion.
That is why Mastodon – the most successful of the Fediverse platforms – has been forked a half-dozen times or more into Gab, TruthSocial, and others. No longer P2P and no longer federated (distributed), these platforms leave the Fediverse and go it alone. And with considerable success.
On a diaspora* support form I asked about an installation script, in which I might change the Terms of Service to forbid porn, anarchy, violence, pro-LGBTQIAP content, etc. The reply:
If you’re going to run a right-wing instance, let us know the URL so we can all block you.
That’s the attitude.
And that’s why the Fediverse cannot succeed.



No expense and trouble with having their own domain name (dot com, dot org, dot whatever).
Ads. Lots and lots of ads.
There are perfectly sane and sensible alternatives to Facebook for cry’n out loud!
