>They still read emails. No doubt they're inside Google, Microsoft, Apple. They might not be inside Proton Mail, it uses PGP but keys are stored server side so I wouldn't know.

I don't doubt for a second that they can read specific emails, but to suggest that they have bulk collection capabilities within Google or Microsoft is a stretch. NSA lacks the legal authority to compel that, NSA lacks the money to bribe Google or Microsoft and NSA likely lacks the political backing to put the biggest US companies in such a compromised position.

>I think the US is still among the countries that use SMS a lot.

Sure, but that's increasingly iMessage.
