well 2 main things caused this: 1. the fact that you can backup a game that you don't own on to the hard drive. 2. and the fact that the tools being used to make hd loader were from sony's dev kits that you must have permission by sony to use (kinda like M$ with sdk/xdk thing for xbox) to me software like this should've been homebrew and never to be sold (you can put games on xbox's hdd, do you see ppl selling how to do that?). btw, this story was actually from ps2newz.net, ps2ownz always loves to steal their stories and make it as their own
