The README for that repo discusses Mastodon/ActivityPub: >The problem with Mastodon and similar programs >User identities are attached to domain names controlled by third-parties; >Server owners can ban you, just like Twitter; >Migration between servers is an afterthought and can only be accomplished if servers cooperate. >It doesn't work in an adversarial environment (all followers are lost); >There are no clear incentives to run servers, therefore they tend to be run by enthusiasts and people who want to have their name attached to a cool domain. Then, users are subject to the despotism of a single person, which is often worse than that of a big company like Twitter, and they can't migrate out; >Since servers tend to be run amateurishly, they are often abandoned after a while — which is effectively the same as banning everybody; >It doesn't make sense to have a ton of servers if updates from every server will have to be painfully pushed (and saved!) to a ton of other servers. This point is exacerbated by the fact that servers tend to exist in huge numbers, therefore more data has to be passed to more places more often;
