Idk for most people, but the reason I use proton mail is to avoid google parsing everything I receive to send me ads. I "have nothing to hide" on a legal pov, I'm not a criminal, the worst offence I do is like Jay walking or crossing at a red light on foot when there is no one at midnight. I don't use proton services to protect myself from the law (or in other words to avoid the consequences of my acts), I just want to be a customer instead of a product.
