There's a difference between the protocol being transparent to the clients reading notes and other stuff transmitted by relays and people being able to have the choice of how and to whom their notes and other stuff are transmitted.
The openness and flexibility of the protocol is the appeal to me. I can't code and don't really want to, so I'm relying on others to not be douchebags and ruin a good thing. That's kinda bad, but, it can form a decent community, if it is allowed to flourish.
