The purpose of this post isn’t to be an apologia for self-hosting email. Rather, it is to highlight the oligarchic behaviors that exist on certain protocols (smtp, etc) and to say that we encourage this behavior when we give up and move to more niche protocols (eg nostr?) In the end, they, the Centralizers own the network. It can be done.
