If someone placed a surveillance camera in each of your apartment’s rooms, and you could remove these cameras or leave them in place, what would you do?
Do you think your behavior would be exactly the same, with the cameras and without them?
Do you drive exactly the same, with and without a police car tailing you?
I think there's also a big difference between how one would act with the possibility of someone watching them (who, if they are watching, are doing so only by illegally accessing my personal device) and how one would act with the certain knowledge of being watched by legitimate authorities.
Nuance is a thing that exists.
