I could imagine:

1. Mr evil uses stolen credit cards to buy game licenses.

2. Mr Evil sells those game licenses on this marketplace to Alice.

3. Alice has paid her own money for this game, starts playing it, maybe buys a few in-game items.

4. The original card owner disputes the charges.

5. Now, if the game manufacturer disables the game remotely, they will take a PR hit from Alices vocal complaints on twitter. Yet if they don't disable the game remotely, they continue to loose revenue.
