Newsgroups as in NNTP[1] fits those criteria, no?
Granted, federated bit is more tricky now. Back in the days many if not most ISPs ran a NNTP server. But the protocol supports it.

I used Gmane[1] to access mailing lists as newsgroups, which I've always thought was a much better fit.
Alas as with all good things that was shut down also.
A great service, glad to see it alive and kicking!
news.gmane.io has always worked.
The issue is that the owner of that domain made a mistake and gave the control of the web frontend to someone else who just shut it down.
