> But do you host your own mail server? Do your friends? Does your grandmother? No, but that's not the point. Being federated my friends can switch email providers (keeping their address too if they rent a domain) like they can do with gsm sercice and still communicate with their peers. They can not do that with facebook, teams, slack, etc. And they also end up having 3000 service providers installed on their phones/laptops/whatever. With 3000 logins to keep secure, 3000 software packages to keep up to date, 3000 services sucking up the battery, etc.
