Have you ever used an anonymizing network for your Internet activities? Some of us have to use them for most of our activities, and while you might deem us criminals for that, privacy tech is used for legal activity the vast majority of the time.

Is not the most widespread crime in our world the violation of privacy by governments/corporations?
