Nemo,
That's a bombshell? I've been assuming it for years.
I regularly tell people on the phone that I don't want to talk about certain things. Those who know me understand my reasoning.
Moreover, I assume that not only are we being surveilled, but that everything captured is databased forever for those who might want to build or fabricate cases against us. Take a walk through a city and, thanks to face recognition, a hundred records of where you've been are likely created. Browse the internet and . . . it all gets stored.
It would be wise to stay off the internet... and to put on a burka-mask whenever going out. What a way to live.
