That's the exact line of thinking our lab has been on. Security<-->usability is a tradeoff, and PGP seems to sit too far on the secure end of the spectrum to be useful to most users. We're working on a way to deliver progressively enhanced security, while onboarding less technical users with more usable features.

While mostly true, it's not so clear-cut. While some improvements to usability would reduce the security, there are also things that can be done to make software easier to use and still keep it as secure (for example, in-app help)
