You are looking for an open+federated protocol. Those definitely exist.
Yes I am. Like you know, email.
That's why email is so awesome. I can easily spell out my email address to anyone in the world and they can now send me a message. We don't have to share platforms or apps or OSs or providers or anything at all, other than access to a TCP/IP pipe. And I will then receive that message. No company can interfere with that.
Go find a random nontechnical person and tell them "send me an xmpp" and see if you ever get that message!
Email not only has all the technical advantages noted above, but also the advantage of universality. Just about everyone who has ever used the internet, no matter how nontechnical, will have sent emails so they'll know how to reach you.

Yup, xmpp checks all of those boxes too. The addresses even look the same.
Well, except one.

I covered that too. “The problem is what is popular.”
