To add to your point, I gleaned this from the Economist: " Consumers tend to respond much more strongly to “free” offers than to prices that are only fractionally higher than zero. When Amazon first offered free shipping in European countries, orders surged—but not in France, where by mistake it charged around ten cents. Researchers talk of the “privacy paradox”: when asked, people say that they care much more about their privacy than their actions would suggest." This leads to another issue. If governments and companies are making important policy decisions based upon data, is it fair or right to access their online behavior in addition to surveys, as people often lie in surveys to project a better image of themselves.
