Developers will be using iAd to make money. Many games would simply not be made without that income. You accommodate the advert in return for getting the app for free, or no app. It is your choice. Some developers will offer a paid-for version or in-app purchase for those who don't want adverts, depending on how they view their potential market (an app for teenagers would have different considerations to one for one aimed at an older audience). If you have problem with data usage, you will have to restrict your use of particular apps to wi-fi coverage.
AT&T eliminates unlimited data plans http://bits.blogs.nytimes.com/2010/06/02/att-eliminates-unlimited-smartphone-and-ipad-data-plan/ It wasn't really a huge issue before, but now with data usage metered I wonder if this will affect user perception of ad supported free apps. Whereas before the change downloading ads was "free" to the user, now the user is paying for ads to be shown to them. With feature rich iAds coming online soon, data consumption rate will probably continue to increase.
