I agree that decentralized systems should make things more open/free and censorship-resistant.

However, cryptography can certainly be used to restrict access or add moderation features.

For example, here is a demo of a P2P LinkedIn with ACL: https://www.youtube.com/watch?v=ZiELAFqNSLQ

Moderation powers scare me, but I do know that notabug.io , d.tube , and the upcoming HackerNoon 2.0 have this type of feature. Except it is called "curation" (technically, content can't really get deleted, but a curated homepage can certainly exclude content).

The good news is that the founders of all these apps are working towards user-configurable curation, so you could override who/what/how curation happens. I don't like moderation, but opting into a web-of-trust is, I think, an interesting area to explore.

No matter the good I want to come from decentralization, it certainly can be used for bad. However, its abuse should be less than centralized system, so hopefully that means real progress is happening.
