All of your data is saved by those companies — and many others — correlated, and then bought and sold without your knowledge or consent. You’d think that your privacy settings would keep random strangers from learning everything about you, but it only keeps random strangers who don’t pay for the privilege — or don’t work for the government and have the ability to demand the data. Power is what matters here: you’ll be able to keep the powerless from invading your privacy, but you’ll have no ability to prevent the powerful from doing it again and again.
Bruce Schneier, Surveillance and the Internet of Things, 2013
Our society has one great knack above all others — one that no other ever managed — that of holding the mighty accountable. Although elites of all kinds enacted laws and customs to hold commonfolk accountable, never before have citizens been so empowered. And history shows that this didn’t happen by blinding the mighty — a futile endeavor that has never worked. It happened by insisting that everybody get to see. By citizens demanding the power to know.
David Brin, The Transparent Society, 1998
