There is probably not going to be an email service that does not share protonmail's threat model, i.e. national police investigation. A nation state has leverage, if the people running the service don't want to go to jail for you (and let's be real, people who would are outliers), they're going to comply with legal demands. What people are looking for is a technical solution to a political problem.
