There was a court case here a while ago because the feds wanted access to someone's emails. They won the case and forced tuta to build them a way into their system that allows them to get at non end to end encrypted emails before they get at-rest-encrypted. German article https://www.heise.de/news/Gericht-zwingt-Mailprovider-Tutano... English article about the same topic https://hackread.com/encrypted-email-provider-tutanota-backd... This essentially means they are forced to save a copy of the non encrypted emails somewhere, at least for german customers. You can argue its not a "backdoor" in the typical sense, since end to end encryption is still in place, but like, come on

Hi, Tuta Team here, we came across this and wanted to jump in. The facts are correct - thanks for explaining it the way it actually was. We explain in more detail here why this case highlights the need for *end-to-end encryption* and why we recommend everybody using it whenever possible: https://www.reddit.com/r/privacy/comments/ntzn3w/comment/h0v...
