The horse has bolted as far as Internet Privacy goes
You are delusional in believing that encryption on its own is THE answer to internet privacy?
Call me naive but I think that the horse seemed to have bolted some time ago and all of this encryption activity we are seeing is just window dressing and feel good fluff!.
The Wiki Leaks put paid to the belief that the internet was private. Slowly since those early revelations we have seen a growing move to utilise encryption technology to protect our data and email communications from prying eyes on both sides of the fence.
