Good explanation, and I figured the same.

I feel the ‘encrypted at rest’ is then a false sense of security. Alas it is much better than gmail, etc.

excuse me ignorance, but I understand that once you receive mail from someone with shared pgp keys, they’d have no way to read the contents.

But when I receive an email from any service that sends me mail, or from a friend that doesn’t use PGP, it sits encrypted in my account… but how do we know proton isn’t ‘reading’ the contents when it is delivered and before it is encrypted in the account?

Is there a possibility of data mining or them storing the contents on their end? like a mirror image?

why would communism do this

If in the future i’m ever forced to drop smart phones because of further proprietary/removal of open source option then i’m definitely going this route.

have a dumb phone and just rely on a good laptop.

On second thought… maybe this is the way.
