As much as I disagree with piracy and what not, this is a frivlious law-suit if I have ever heard of one.
First off, it\'s the user\'s computer. He has the right to know what is going on his computer and he also has the right to disable any features he does not want active at any given moment. You can say he is bypassing copyright protection - but come on, maybe someone doesn\'t want it to autorun the installer? Maybe people want to know what is going on with their computer? If they win this lawsuit (and I doubt it) then expect a lot more stupid lawsuits in the same vein.
Plain and simple: The owner of the given computer has the right to disable features. He / She has the right to know what is being installed. If the company wants to make a secure copyright protection, that\'s fine. However, don\'t complain when you come up with something so simple and stupid and the common user can disable it with one finger.
