Even with the XBox's terrible reputation in terms of its level of reliability, doesn't the same thing happen if you rotate any machine while it's running with a disc inside of it? My Matsui mini system sometimes scratches my CDs if I knock it accidentally while the disc is rotating inside it, and a number of my CDs have scratches of the same shape, although the scratches aren't deep enough to have much effect on the playability. But I have enough common sense to know that I shouldn't sue for my own mistakes.
