I apologize for not being clearer. Even in my relative youth and ignorance I make broad assumptions about others understanding of the recent histoy of VPNs and omit stuff I think is simply known because naturally everyone who would post on the privacy board has been keeping up with privacy and security news for the last decade.
I made another reply that explains in detail why and how mullvad can be trusted in this situation. Hopefully it’s a little less scattered, but I can clarify anything that seems wrong or weird.
The point I was trying to make about mail was that you’re better off treating it as a postcard that anyone can read than seeking a privacy respecting service. That simple change will improve your posture because you will no longer be communicating private matters in a medium that isn’t private.
