Somewhat true if you have anyone left who wants to talk to you by email.
First people stopped using it for socializing, and now it’s slowly on the way out for work communication too IME. Not secure enough. Better to use a secure messenger which requires login. And personally I quite like this, assuming the messenger is on the web and requires no software install.
The reality is that the main surviving use case for email is as a notification engine.
Then you’re doing exactly what you are supposed to do. Disengagement, hopelessness, resignation, it’s all in the authoritarian playbook.
Addendum: To be clear, IMO what you Americans need to do is stay engaged. That doesn’t mean protesting everything (personally I think that might even be counter-productive). It does mean voting at every tiniest opportunity, you have lots of them. And if possible getting involved in some form of local politics, even if that is just joining some club or association. It’s like a tyrannical boss and his employees, what authoritarians hate most of all is for their subjects to be talking to each other.
