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.
