Mind talking me through the ethical problems of copyright infringement? I'm not a fan of copyright in general, and from that perspective, I fail to see the problem in copying files.
That problem is largely irrelevant to copyright infringement. All copyright infringement (within a rounding error, exceptions obviously exist) doesn't actually hurt plucky artists from whom starvation is a real threat. Copyright infringement is largely a problem for corps who lose out on some money (money which almost certainly doesn't drip down to the actual artists).
