From my understanding, there is no way for ProtonMail's operators to decrypt your mail storage, it requires your own private key. Whereas FastMail is not much different from Gmail in terms of "company's access", except it's privacy policy prohibits it from using it for anything but customer service on request.
Is this just TLS + block level encryption like LUKS? If so I would be surprised if FastMail wasn't offering the same. But maybe Proton is offering something else at the client level? It was my impression that the big differentiator was Proton Mail's infrastructure was all co-located in Switzerland.
