I was with you right up until the end. I think the only thing that would stop me from sabotaging a small project like PGP (was in the early days) is moral aversion. FOSS and academic circles where these things originate is generally friendly and open, and there is plenty of money and length of rubber hose for anyone who doesn't welcome the mole into their project.
I'm not saying I have evidence that this happened to PGP specifically, just that it doesn't seem at all implausible. If the CIA told me my code was never to get too easy to use, but otherwise I could live a long and happy life and maybe a couple of government contracts it would be hard to argue.
Why a mass-market interface never took off (GPG and other descendants notwithstanding) may indicate that the whole cryptographic idea is inherently not amenable to user-friendliness, but I don't find that hypothesis as compelling.
(It could also be an unlikely coincidence that there's a good solution not found for lack of looking, but that's even less plausible to me.)
Then why no such efforts are being pursued for PGP(GPG) nowadays?
signify[1] is approachable at least for the power users - I could print out that man page on a T-shirt. HTTPS is ubiquitous and easy, thanks to ACME & Let's Encrypt. E2EE with optional identity verification is offered in mainstream chat apps.
And of course there are usability improvements to GPG, being made by third parties: Debian introduced package verification a couple decades ago, Github does commit verification, etc. What's to stop e.g. Nautilus or Dolphin from introducing similar features?
you'd think if the cia don't want it to happen, then somebody somewhere else would make it though. it's not like the CIA and fsb would collude - they serve different oligarchs.
