> but I don't believe it should be considered insecure unless you are a journalist, activist, or citizen of a country with severe oppressive regimes: China, Iran, Saudi Arabia, Turkey, Russia, etc.

If only those people will try to have privacy, it will be much easier to target them. Everyone should have privacy to protect them. It’s sort of like freedom of speech is necessary not just for journalists, but for everyone, even if you have nothing to say.
