Any society in which people interfere in the private lives of others is not a good society; any state in which the government 'knows about you more than you do' is a state that must be overthrown.
Do you know what the true basis of political power is? Not weapons or troops, but the ability to make others do what one wishes them to do.
We have a lot of leaks in our reality.
