Yes surveillance has been around since authorities have been. But that's not what we're worried about.
Were worried about having a profile on the worlds largest data processing plant. Yes a profiling supercomputer which has the ability to connect absolutely everybody in the western world to something illegal.
Yep, every personal joke you've sent on WhatsApp which is self incriminating, every time you've logged into your Gmail from a network where someone was searching for explosives earlier, every person that replied to my Mac-10 thread.
There's a difference between classical surveillance and this evil mass incrimination charade these guys are implementing. In 10-20 years they will be like "Everybody is a dodgy scum, we must install CCTV in your house, have GPS tracker factory installed in every car, seize ultimate control of the world, and remove what rights you have left" and the citizens will bend over backwards and be like "No problemo I don't have anything to hide".
