I don't know if that will help. You can already lock down iOS pretty tightly for kids. It's the apps themselves that are the problem.
There's just a huge, annoying trend of making apps crippled or annoyware until you buy some ridiculous IAP. AFAIK, that situation is not much different on Kindle/Android.
