The fediverse is based on the fundamental philosophy of the network effect. Idea is that once the fediverse has a large enough user base existing outside of that is impossible.

I’m simply saying their are enough right wing and centre people who use social media that an isolated hard left echo camber cannot exist as an isolated island. Federation enables a true marketplace of ideas a true bastion of free speech. It is unstoppable it is inevitable. No instance shall centralise it but the majority of the people who use the internet expect to be able to interact with other using it.

A majority of users on politically neutral instances will kill isolated extremists who don’t federate. lemmy.world and lemm.ee where the first to prove that and its only going to grow. Information craves freedom and censorship will always lose.
