In the case of email, security is more important than privacy. The country your provider is based in doesn’t matter.
Hypothetically if we were talking about something like a VPN, it would need to be a country which values privacy and which has a vaguely hostile attitude to America. I have no idea what country that would be.
They’re two sides of the same coin. Can’t have privacy without security and can’t have security without privacy.
Looking at the post though he’s specifically talking about advanced security as a means of preserving privacy, security you’d need if (based on his model) targeted by a government (whether foreign or your local police forensics team). I don’t think his model is correct though because while extra hardened security is useful to protect privacy in such an instance, it’s also just best practice because it’s better to have too much security than not enough, just to keep your bank account secure at least.
I find iPhones themselves dystopian.
Why not. Not like that money would be put to better use elsewhere.
