In the end, I trust them more than any other email provider. Also, if you have a life, hosting your own email on your own server is not a good solution, I’ve tried it more than once… super easy to get going, hard to maintain. So proton it is for me, and without proof of nefarious activities I think it is unfair to attack them. Complying with the law is not nefarious. Know your threat model and it shouldn’t be an issue, because if you really had something to hide you wouldn’t use email in the first place.
