The damage has already been done.

Between Facebook, Google+ (which Google is trying to force down the throats of all Android users), everybody's cell phone contact data, all the smart phone apps which collect data, voice samples, pictures, etc, Big Brother already knows everything there is to know about you as well as your business and social contacts.

When the next dictator makes his move to enslave the people and suppress dissent, people are going to be shocked at the efficiency of the evil. Truely scary times.
