I disagree, I think you cast the net way too wide. Asymmetric cryptography enables secure communication in the first place. It's being used nefariously by Google and Apple, of course, but that's to be expected from big tech.
Isn’t the ability to create certificates guaranteed conceptually once you have asymmetric crypto? In that case there is no intermediate technology which allows key exchanges without also creating digital totalitarianism.
Nefariously how?
