PGP doesn't have this problem
Sounds to me like you used a specific piece of PGP software you didn't like or understand.
How can you folks care so much about your privacy, but absolutely refuse to understand the tools you are provided that ensure your privacy? You're never going to get it if you demand it be provided in a blackbox app you don't have to think about.
ProtonMail uses the PGP standard. Its UI is simple and easy. There's still one issue: You're trusting someone else to do your encryption for you.
And yes it's great that some tools manage to hide PGP, it's not easy to do.
The problem, maybe it's not us, maybe it's PGP?

Don't get me wrong. PGP is great as a simple standardized cryptography protocol intended for messaging. It should be used just for the standardization. The cryptography of encrypted messaging is an easy problem and has been well solved. We need to move on to the problem of how to explain it to the rest of the world well enough so they can use it.
