Thanks for the "how" - I guess if you fully control the client and server, there's some extra checks you could implement client-side based on the cryptographic root of trust.

FWIW, I wasn't really trying to make a prescriptive statement about how the world ought to be, I was more trying to describe what (I think) the perspective of these corporations has been on the matter.

In the past, I've been an encryption advocate with the knowledge that we (tech) must sacrifice some ability to appease politicians in implementing it. What you're describing sounds like an innovative way to preserve privacy and provide security for at-risk people, which is a perspective I haven't heard before.
