Facebook and Google Don’t Need Your Data to Make Lots of Money

These are all weak arguments. There is no reason to fear that sites cannot still make money with advertising. That’s because there are already two kinds of highly profitable online ads: contextual ads, based on the content being shown on screen, and behavioral ads, based on personal data collected about the person viewing the ad. Behavioral ads work by tracking your online behavior and compiling a profile about you using your internet activities (and even your offline activities in some cases) to send you targeted ads.
