you’re right about the IP thing. that’s a good clarification rather than just “spy”. i suppose it’s less dire than Tutanota not encrypting incoming mails if you use tor and vpn by default.
yeah basically it more or less proves that swiss privacy is a bit stronger in this case vs Germany.
on the proton encryption, i did know about this but does that apply to proton-to-proton, proton-to-NonProton, or both? if you have details on this let me know.
either way the fact that they dont makes me feel that proton is a similar honeypot to signal and telegram, where they make a compromise with the five eyes, to give them metadata even if actual contents are safe. metadata can be much more powerful than contents often times
in general email is just the worst protocol when it comes to privacy. sadly.
