"Licences do not apply to copyright,"

I'm going to stop you there and suggest that you go do some reading. Your understanding of the legal terminology is too woefully wrong for you to participate in a productive discussion of the issue. You are making sensationalist statements ("sued for simply looking at open source code") that are either extremely misguided or disingenuous. If you want to participate sincerely, you need to put forth more effort to understand what's at issue and to communicate using the correct meaning of technical terms.
