There surely is, but the first step is to acknowledge that the world has come to a certain point where we've lost control of our data and intelligence agencies, and not to write off people who's privacy has been compromised as fools who should have known better.

Because we are all those fools. Do you use gmail? If you don't, do you email people who do? Do you use Facebook? Do people talk about you on Facebook, even if you don't have an account? Do you email people who give Facebook their contacts? Is that even something you can find out?

Trust is transitive. If someone close to you along your social graph is being observed, you are being observed indirectly. If many people around you are being observed, you are being observed rather closely.
