You're describing the indieweb: your identity is decentralized and is your domain name (not at the whims of billionaires), you put up whatever content you want but typically articles, interact with other people's content (likes, retweet, comment) without the need to create an account anywhere.

The real blocker is that in practice there is a huge step between creating an account on a commercial service and buying your domain name, setting up a website and making it reachable to the world.
