The real win here would be access to server side code - account management, loot box rates, plus garden variety buffer overflows and hacks. Open or closed doesn't matter as much if it runs on a device you can control, you can always reverse engineer it. But for code you'd never get to run on your own device, you have more limited tools at your disposal. Even if they only got binaries of the server side code it'd still open up a lot of avenues.
