I'm actually surprised that most people don't understand the simple fact that nothing is free. Nothing.
Those so-called free apps aren't free either. They take your private information, daily activity, interests, and a lot of other things and then sell that information to the big daddies of the consumer world so they can show you ads containing products that will be almost irresistible for you to buy.
Yup, everything is being mined, and ads are being targeted at us base don data being collected. Great video.
