the second I read "build apps" I knew this is not even close to an alternative models.

the only alternative model is decentralized, encrypted and pseudonymous/anonymous. Maybe something along the lines of btsync, btchat mixed with pursuit [1].

Tent is decentralized-- most Tent apps connect only to the user's own Tent server (they aren't hosted and don't "phone home"). Tent supports client-side encryption and strongly encourages anonymity.
