It sounds like you have no idea what money laundering actually is, to be honest. Money laundering is concealing the source of illegally obtained money.

You use stolen credit cards to buy gift cards (or just defraud people to obtain gift cards). This is dirty money.

You pay it to yourself on the App Store by getting an app listed and buying it. Apple then deposits money (minus their 30% cut) in your bank account, which is clean money.

How is that not money laundering?
