As technologists, we're often the ones implementing and designing the systems, infrastructure and algorithms that make such a thing not only possible, but likely :(
I once worked at a place that was bidding on surveillance tech for some public transit systems in Australia and the cavalier attitude that management had about privacy was sad, to say the least. They just didn't think it was their job at all to decide what is right or make any ethical judgements whatsoever. To them, mass surveillance was merely a way to make a lot of money and that's all. They didn't care who got hurt when that tech eventually makes it to less democratic nations to be used to suppress and destroy the human spirit.
Well, that company went under, but others succeeded.
