If you don't know who has your credit card data, at any given time, including your children, perhaps you should start there! Why yes I do take due diligence and confirm every charge on my credit cards, debit cards, and bank accounts. Do you not? If not, do you trust your children with that information?
Not a problem I have, really. I don't have kids, and the cats haven't learned how to use my plastic yet. But, hey, you just congratulate yourself for being so diligent. I'm sure it's relevant to the discussion somehow.
This a technological window kids are exploiting because their parents gave them sufficiently advanced technology. Sometimes parents should tell their kids no. Don't do that, or I'll take that smartphone away.
I think the issue is more that the payment system didn't allow enough feedback for the parents to determine that their credit cards remained authorised for in-game purchases. And While it's all very well to read the riot act to your teenage son for abusing your card, it's hard to do that to a six-yearold that didn't realise all that extra time on candy crush was costing his mother actual money.
I'm also not convinced that disclaiming purchases on a card is an adequate substitute for a payment system that allows you to manage access to cards securely.
As much as people want to lambast Google for this, and I'm sure they'll now change it to auth for every app install, the idea of controlling this problem starts in the home.
I don't know about lambasting them, and I agree that if they've got any sense they'll fix this asap. I just I don't think they're entirely without responsibility. And I certainly don't think you can dismiss the issue by saying "ho hum - all the parents fault" as the GP attempted to do.
