If you think you have any privacy anymore (or have had any for decades) you are pretty naive.
There are so many ways you can be spied on, there is little you can do about it too. Not just using the tech of the last two decades either. Even older tech is still good too, and still used I imagine.
Take the telephone. Yeah, the police or the feds aren't listening to every call, but some phone company tech can and will hear phone calls. Just clamp a test set on, and listen away. Doesn't even have to leave the central office too. It's not even hacking even. There is no security at all on a phone line.
