It very much depends on your local laws. Despite the current administration, the law in the US, for example, is that you do not have to divulge passwords (a Fifth Amendment right to silence). You can hand over your entire encrypted database intact, no destruction needed, and unless the authorities can decrypt it, it’s useless evidence in court. Prosecutors may still try to build a case without that evidence (as you pointed out by getting decrypted correspondence with an accomplice), but it’s not illegal to hand over encrypted data, even if they demand that you decrypt it; you are under no legal obligation to help incriminate yourself.

That right may not exist in other countries, so as always, one should know their individual rights and threat model.

Right. The point is that they’re not going to do you any favors with regard to the law. They have zero incentive to fight the law on your behalf, because your relationship is purely transactional.

Another way to say it is, “No company is going to break the law for you.”

For all questions: your own.

Every company has to comply with the laws of the country in which they operate, and no company is going to go to jail for you. There’s other encrypted email providers, but they will still have to abide by their local laws. The best you can hope for is that they have minimal data on you and that anything potentially incriminating is encrypted and can only be decrypted by you.
