If you think they don’t have to, be my collective I know that it is currently en vogue to throw the word “conspiracy” around, but like most you obviously don’t understand what it means. I don’t want to destroy any LaLaLand fantasy some of you might still hold, and I also never expected ProtonMail to say “Yes, we do it!” when accused of doing it, however it is clear as day that they must comply with Swiss law. ProtonMail is headquartered in Switzerland, therefore it has to comply with Swiss local surveillance laws well, unless you want to imply that they are operating in Switzerland illegally, which is extremely likely for a service as prominent as ProtonMail (haha).
