I do not understand the issue here.
What is the argument? That the Apple is somehow forcing parents to give their kids access to their accounts without question?
Let me lay out two scenarios here:
Your child asks you if they can please buy a .99 cent smurfberry. They have been very good today and you are feeling generous, so you oblige them by inputting your itunes password and letting b them buy the requested digital item. Later on you discover that they then abused your trust and bought all teh smurfberries.
Reaction: Sue Apple for publishing addictive games.
Your child asks you if they can please have a .99 cent icecream bar from the local shoppe. They have been very good today and you are feeling generous, so you oblige them by giving them your debit card and PIN to buy the requested delicious item. Later on you discover that they then abused your trust and bought a few CDs as well as the .99 cent icecream bar.
Reaction: Sue W.B. for publishing addictive music.
This does not make sense to me. Parents can not offload the responsibility of raising their kids to society at large. Are these games designed to make kids want to buy things? Yes. Does the fact that they are digital goods make it much easier to obtain then traditional items? Yes. However, if you as a parent do not teach your kid that stealing from you is wrong, no mater how colorful the end result is, you have failed to do your duty as a parent.
Kids are tempted to do all sorts of things that are bad for them: eat candy all day, not go to school, call eachother hurtful names, etc. Leaving your kid unsupervised with your passwords is not the fault of Apple, or W.B., or anyone else. Would you blame your cable company if your kid ordered PPV TV because you told them your password?
