That said, Russia banning Proton Mail is one hell of an endorsement for Proton Mail, in my estimation. I want to believe in the dream of ubiquitous end-to-end encrypted email. I don’t know if Proton is the right manifestation of that, but it certainly doesn’t hurt in terms of keeping the dream alive. So, I wouldn’t want to wave anyone off Proton, even though Fastmail is a great service.

I think the major problem with any PGP Mail system is that nobody else uses it. I have a semi-technical friend who, for ideological reasons, decided to switch to Proton Mail. I dusted off a GPG-capable email client and provided him with my public key. After some technical headaches we exchanged a couple of emails and promptly went back to organizing the occasional happy hour or movie outing via Signal.
