Amazon Refuses to Settle with FTC Over In-App Charges

For the longest when you bought a kindle, it came pre-setup with the purchasers card details prepopulated. So after the initial setup steps, all you had to do was tap One Click Buy, and boom. Your kid just bought it. So it was kind of a scam, they knew what would happen, and you couldn't even remove the credit card and use a gift card.

Not to say parents should take no responsibility but still.
