Most of us, most of the time, use immensely popular technologies without masks or noise. We post in what you might call corruptible silence. On Facebook, Instagram, Twitter and Google, we document our personal spaces, our frailties, our desires, questions and answers. We are naked, exposed and eminently traceable, now and into the future, by an ever-increasing range of data-hungry agents. To concerned citizens living this reality, and to thoughtful designers of technology, what Brunton and Nissenbaum offer is a compelling moral defence and some ready-to-hand tools for a small, distributed revolution of resistance.
