It seems obvious Five Eyes will not tolerate or legitimize any email provider that doesn't allow them access to subpoenas, at the very least - this rules out most of the privacy features touted by protonmail & tutanota (no logs, E2E encryption, etc).
Perhaps what makes the ruse convincing in Tutanota's case is the crappy interface and clear dearth of basic features: search basically doesn't work; it's impossible to select all messages or use shift to select pages of messages. Their excuse is that customers might accidentally delete emails, but it might make more sense that they want to retain as much data as possible: https://www.reddit.com/r/tutanota/comments/nc9jxx/suggestion...
