That's only a limited success, because I still trust the US Government, even NSA, more than almost any foreign government. (NSA has more resources, but there's at least some semi-effective political and thus popular oversight).

The ultimate solution is providers which can prove their operational security to end users continuously, through technical controls.

Could you elaborate on that first statement? Would you really place more trust in the US government in these matters than, say, the government in one of the Nordic countries? Or Germany?

Trust in a government is mostly relevant in situations where they would be breaking the law, like spying. If the law doesn't protect you in the first place, then the trustworthiness of the government doesn't really matter.

If the courts decide that you can't be compelled to give away master keys, then the US is a good choice. If not, no amount of governmental honesty can protect you.
