Why is that? If you buy the game off Steam or something, this implies that the creators/publishers/platforms have gotten their due compensation. The cracks and files on ThePirateBay are done on a volunteer basis, meaning that it’s not costing the game developers any money.
Maybe lay off the eggnog or before reading HN so that you don't comment this poorly w/o reading the thread... They've bought it, the Dev. Got whatever pittance the publisher seems worthy, they just want an experience unadulterated by crappy launchers or corrupted by overzealous DRM.
Is there any chance you misunderstood? They said they wouldn't feel bad morally about pirating things they had in fact already paid for? Does your ethics require you to stick to the letter of the terms and conditions including allowing people to keep your money and take back the value they promised you?
