It's the refund policies that are being questioned, you being aware of a charge doesn't mean anything when Facebook doesn't refund it.

So your child spent 6k$ and you are now aware of it. So what? This article specifically talks about the employees who talk about child as whales when discussing whether to refund or not. Presumably the 5 year old kids did not request the refund themselves.

You read an article about predatory practices and somehow you now want to place the blame on the user?

How about we don't do corporate apologism eh

No, I read a comment about parents who apparently don't check their credit card transactions for months at a time.

It isn't ethical to exploit children who have stupid parents.
