Kottonballs I've tried to find proof of Proton turning on logging for a user but can't seem to find anything.
French police arrested a climate activist in September 2021. Proton were legally compelled to turn over data related to the IP address certain emails were sent from, and the IP address was useful in engineering the arrest. My understanding is it was just simple internet traffic logs that were turned over (they didn't break encryption on the emails or anything like that). Legally, Proton had no way out of it and no option to appeal the request. If they tried to illegally conceal the data, they would have been shut down, and Proton employees would have been arrested.
Proton CEO Andy Yen responded to the event in a blog post here: https://proton.me/blog/climate-activist-arrest
I think an important thing to note is the whole thing would have been made impossible if the user had simply connected with Tor or a VPN to send their emails. Proton even offers an onion site (https://proton.me/tor) for anonymous access--very uncommon for an email provider--which is a resource this person obviously did not take advantage of.
This is basically a case of user error. Considering they were under criminal investigation, they were frankly a bit careless. It seems unfair to blame the email provider when a user cannot take even the most rudimentary precautions to protect their anonymity.
