@mastodonmigration I would express it differently: if a network has economies of scale baked in, it is centralised, even if you don’t know it yet. So it was with the web, so it is with email, and ditto for ActivityPub/Mastodon. Federation is better than nothing but there is nothing in the protocol or in its big-tech stack implementations in the popular clients to prevent centralisation. The best tool we had was social pressure and that lever was summarily disposed of early on when the only folks who could have used it decided not to.
