Technology for oppression and change

Technology can be used for oppression because if the government puts of cameras everywhere and track your cellphones like they did in china, then nobody could get their word out because the government will track it. And if people cant get their word out, then no movement will happen and nothing will change. Technology can also be used to change something by people creating groups on Facebook like they did in the middle east. Also people can use technology to communicate with other people. And once people communicate with each other, change will happen.
