content: That is the thing the price difference and as the headline says it just slows down the rate of sends. The article says nothing about what is begin sent to Apple or the volume of data like it mentions for Google in theory the headline is true if Apple collects 2x as much data but only sends it 1/10th as often. We are given many acts about Google in this and just one in the headline about Apple.  The overall conclusion of the research is that Google tracks its users more often and collects more information about their movements and behavior when compared to Apple or to Google's ability to track users on Apple devices.  That leaves open what are they defining as "behavior" because that is going to be the decider on where Apple lies on this. Then again if you are posting everything on facebook and telling people where you are going and when you get there as well as when you leave and when you get home, the tracking becomes a moot point anyhow.
