Lmao nah. Lemmy is just decentralized censorship. Anyone can ban or block anything else; anyone can start their own community instance and kill it on a whim. Multiple communities have already defederated in the less than a year that I've been on here.
Lemmy solves the issue of centralized censorship/echo chamber communities, by replacing them with individual personalized echo chambers that you get to censor yourself. It's a lot of work to set it up and sustain that type of situation, so it's not realistic for a rational person that does not have a severe internet addiction to waste their time and effort doing it.
