The freemium app craze drives me nuts. Used to be, the way to get more revenue from your game was to make it better. Now game creators are getting more revenue from their games by making them worse. That's a great example of win-win versus win-lose transactions.

Note that I have nothing against game creators charging for their products, it's just that the freemium model is pretty much inherently built such that creators make their money by making the game less fun to play.
