Proton Mail's extremely bureaucratic operational deafness, and their glacial pace of product features and open-sourcing, would certainly lend support to that idea.
I actually wish this was true. I want an email service that would last forever and is secure enough from my threats, namely security breaches of the email host and account takeover from non state actors.
Gmail is close enough, but I want an alternative. An email service run by the nsa or the cia would be great.
To address the broader topic of this thread, there is no comparison between Crypto AG and us. Our encryption occurs client-side, our cryptographic code is open source ( https://proton.me/community/open-source ), and our tech can and has been independently verified.
