P2P services like the article suggests are impractical in real life. It's of extreme importance that you should be able to view, and preferably interact with, something posted on a social media service with as little friction as possible — which means it has to have a web version, and that all content within must have permanent HTTP URLs. No one will be downloading a client and syncing it to the P2P network to view a post or to comment on one or to like one. This has never worked and never will, because it's inevitably a messy experience. ActivityPub is basically as far as one could push the decentralization of social media without severe UX compromises.
