It is easy to task authorities with intercept and decryption duties; actually doing it successfully is another matter entirely. Mathematics works both ways, friends.
Actually if Apple, Goog, FB etc are forced to surrender the key--at the penalty of being excluded from 1.x billion people in India--math works only one way...

It would take a large-scale public education campaign to teach people what it means when they see a warning message that reads "Peer key changed. Are you sure you want to proceed?"
