Do you really think Google would sell the core part of their business (your info for ad targeting) to others? Does coca cola sell their recipe?
hehe. What is "core" nowadays anyway? Some info is more equal than others.
Google sell the changing behaviour ... a single snaphot has low value over long time... Did you really think they did it for free? Apart from paying for the ranking - Someone pays for all those datacenters and infrastrucure all over the world (and its not end-user donations). Their business model is a decade old.
FB has another angle - they have two angles of you. And we know the value of our personal and unique Joe Bloke profile information was calculated as $28 (whatsapp acquisition price)
I just hope it will be a good DLC for that sell. The in-game adds /logos never really took off.
Maybe we can propose that they take the youtube route. Halfway through a game, a 4s ad must pop-up- you either wait or pay a small ransom microtransaction to continue immediately...
