Your last statement is false. A shady merchant never gets to keep the stolen money. The card issuer/bank refunds you immediately because of consumer protection laws. But that charge is immediately charged to the processor. The processor then gets the merchant involved in a dispute process. If the merchant loses the processor charges the merchant. One way they do it is to immediately deduct it from their current processed transactions. If the merchant is no longer processing, they will usually go try to claw it back from their bank account if they have no held reserves, and if they can't get it, they send the merchant to collection. At the end the merchant must eat the cost or the processor. So in your case, the bank didn't eat the cost. OpenAI certainly ate the cost and the chargeback fees.
