Rolling back a surveillance state and establishing a government with more protection of individual liberties is something that has been done before. I have seen it done. I related at greater length here on HN my experiences living in a surveillance state that included government assassins to eliminate political opponents at home and abroad.[1] Getting rid of such a regime is not easy, but it is possible. It takes courage, and it takes unity among the courageous people making up the freedom movement.
I remind my freedom-loving friends here on Hacker News that there are resources to help you if you really want to be an idealistic but hard-headed freedom-fighter. If you are mobilizing an effective popular movement for more freedom wherever you live, I suggest you read deeply in the publications of the Albert Einstein Institution,[2] which are compiled by advisers who have helped bring about democratic transitions in various parts of the world. Not all of those movements have succeeded yet, but I bet on their long-term success in China, Russia, Saudi Arabia, Iran, North Korea, Afghanistan, and wherever freedom is scarce. Remember that the transition from dictatorship to democracy described in the Albert Einstein Institution publications is an actual historical process with recent examples around the world that we can all learn from. Practice courage and practice collective action.
