> I'm left feeling that traffic data produced as a side product is somehow being reused internally Of course. One has to be very naive to believe data traveling to their servers is being immediately discarded. This reminds me of a story I saw once by Onavo, a mobile app which reduces data usage by acting as a middleman and compressing the data before it reaches the phone. The story however talked about which apps made the most revenue; and guess how they knew: http://techcrunch.com/2013/01/08/onavo-mobile-games-grossing/ http://techcrunch.com/2013/01/08/onavo-mobile-games-grossing... The company looked at game usage among their U.S. iPhone users in November. Then they looked at the market share, or the percentage of their U.S.-based iPhone owners that use these games on a monthly basis.
