Short: DRM

 Video games often come with some kind of copy-protection software - typically an obstructive, pain in the ass load of bloatware. The copy-protection software attempts to ensure that only legitimate copies of the game are in use, which means that pirates are forced to first remove the copy protection from the game before playing and distributing it. The tragic irony of the whole situation is that the pirates, and only the pirates, get the bloatware-free copies of the games. Not only do pirates get the product for no cost, but they also get a better product! This, while the legitimate consumers are being shafted in exchange for their loyalty. Well played, game publishers.
