I'm very excited about Sovrin and other Self-Sovereign Identity solutions. As one of the engineers at Mainframe (we're building decentralized, unstoppable apps that keep data and relationships in control of the user) I think what you're talking about is one of the top two value-adds for decentralization for western societies. Brave and BAT are attempting the same thing from a slightly different direction than we are--they are attempting to bring privacy to partially-decentralized apps; however, I don't think this will ultimately succeed--privacy is broken by the weakest link. As soon as you allow some connection to some server somewhere that's exfiltrating your interests, you now have advertisers lining up to buy that data and exfiltrate more. As far as I understand the "hybrid decentralized app" model, where DNS and web2.0 are allowed, you permit these weak links to exist.
