"Now there's a chance this is just a prank from some Rockstar programmer, perhaps playing off the trouble Ubisoft ran into in 2008, when a no-CD hack from piracy group Reloaded was used in an official update to Rainbow 6: Vegas 2.
Or it could just be a lazy programmer. If the tool exists that gets the job done faster than creating a new one, why not use it? Of course, speaking out against piracy becomes a problem when you use the products of piracy in your official releases, but surely this won't upset anyone at all, right?"
En otras palabras, puede que estén de coña con el tema, o puede que símplemente hayan decido aprovechar el trabajo del cracker original. Al fin y al cabo, quien roba a un "ladrón"...
