Its not about slave authors wanting money. anyone is free to write a slave for there favurate game. The compilations usualy find there way onto ebay as well so someone is making money out of them. The cd compilation will work absolutly fine without a key so there should be no reason to spread one on such.
One good thing about whdload key piracy is that each new whd version updates a blacklist of known pirated keys making it just a little harder
