So you probably won't pay for the game and don't want to have ads to compensate the developers of the game. How do you expect to continue to get quality apps in your perfect world?
If even 10% of developers actually gave me a choice, you'd have a much better argument. In fairness, indie games often do, and I often pay for them, and I have a much higher tolerance for ads when trying out the free game.
Other issues here are that I often turn off wifi for other games, then don't turn it back on until I've got a decent reason to do so. Today, iPads are more enjoyable with wifi off because of the ads that really push it.
I think it's also a function of the fact that free apps sell better, and that makes them more likely to get my attention in the first place. When I want to find an app, I want to find a "good" app, so I often use the top selling lists, which are much more likely to have ads.
