The police gained access to the IP address because Swiss authorities chose to cooperate with the French government

We’ve seen this several times now. Proton is subject to Swiss law, just like every company in their respective countries. You choose Proton because Switzerland has the most privacy protections of any country on the planet (for now).

If you want private communications, don’t use email. In fact, if we could all stop using email entirely, that’d be wonderful. There are hundreds of truly-private alternatives, many with no company involved at all.

It’s also worth clarifying that ProtonMail doesn’t collect IP addresses by default. Instead, the monitoring/ logging starts after ProtonMail gets a legal request.

They still have to adhere to legal requests.

Apart from it’s an old story, discussed already back and forth, Proton’s claims regarding privacy are really weak. Especially when it comes to presenting Switzerlamd as a privacy safehaven. Switzerland is a tax evasion savehaven, not a privacy safehaven, Proton. How Proton puts it: we provide world class privacy (but have to break our claims and comply with Swiss law immediately once there is a legitimate or not request from law enforcement, oepsie sorreyy!)
