Quick! To the Space Shuttle!!!
If I've gone through all the trouble to make sure all my workstations have licensed versions of -say- AutoCad (5000$) and my competitor has simply cracked it then I want him stabbed in the ass. Its that easy. Some companies will do anything to take out a competitor and if they have cracked software might as well report them. Not going to do that with some jerk down the street downloading limp bizkut.
