An anonymous reader writes "Why are there so many free games listed in the top 10 grossing games over in Apple's App Store? Because some feature exorbitant in-app purchase fees for virtual items. Quoting ZDNet: 'Developing "free" games aimed specifically at children, and then bundling ridiculously priced in-app purchases inside those "free" games feels scammy to me. Sure, it's not illegal, and it's not against Apple's developer terms and conditions, but Apple is a company that prides itself in protecting users from harm. Most of the game developers do make an attempt to warn users that the game "changes real money for additional in-app content" but it's a lame attempt. It's easily missed, and kids aren't going to read it anyway.'"
