I think Rovio is putting all their weight into turning Angry Birds into a global brand. The mobile app market is still pretty limited. Getting beyond $10 million revenue over all is incredible but nobody has any experience on sustaining success in the mobile market in the long run. Investing in the brand, on the other had, gives Rovio a lot more options - licensing deals, a movie deal or whatever. It is a tried and tested model. If Rovio got 7 million extra fans and alot of free media coverage by releasing it for free on Android, that in itself might be a better deal than a half a million in revenue from sales, even if you don't count the advertising revenue.
