Yeah, so Ruqqus does something very similar at the moment - using "guilds" and allowing individuals to maintain their own. The problem is with the people that the platform attracts - basically every guild on Ruqqus is something along the lines of "blackcrimesmatter" or "wakeupwhitepeople" not because the site is explicitly disincentivizing people with other beliefs from joining but because the audience is self-selected (people who think Pepe is a symbol of resistance) and because it's hard to end up with a diverse userbase. Decentralized networks where participants interact are still bound by the laws of human behavior, and people aren't going to frequent a space where they aren't welcome. The reason that Matrix 'works' is because there is no cross-cluster interaction: I have a server set up where I can chat with friends, but have no reason to interact with the pretty horrible use cases. Sites like these, on the other hand, are designed to normalize those use cases and encourage you to join those communities.
