I really don't think that is even close to reality as the majority of users don't care all that much about e2e encryption (because they don't understand it) and that same user base has no idea what you are talking about with regard to decentralization. I would even venture to say that I'm not in a tiny minority of professionals that do care about e2e encryption and do understand decentralization but think that decentralization will never be much more than a science experiment. Users care about their experience and they want to have unencumbered conversations. The decentralized dreams impede those things.
