I am shocked, that it is legal to offer simple games which allow in-app purchases of this size. If you compare these games to any AAA title which goes for like $70 or less, this isn't ethical in the first place. With the money spent by a child, there should be no way to enforce the bill. Here in Germany, children cannot do business transactions which exceed the range of typical pocket money, so we are talking a few dollars here. Any business larger than that would require the parents to agree to be valid. Invalid transactions can be reversed. And when pointing out towards parents negligence: keep in mind that there are no multiple accounts on iOS devices and there are good reasons to spend money to buy apps on a device. Of course, with enough understanding of the technology, parents would set it up so that the password is required for every purchase. The question is, is this a reasonable request for non-tech parents? So if Apple wants to be in a position of morale, as they pitch themselves, they should put reasonable limits to in-app purchases, especially towards these games.
