Since Bridgman is a part of AMD and AMD are the license holder, they can do anything they want with the source code (and the disassembled code) as long as it complies with company policies, legal department and so on.
That's the point: AMD is not the license holder for all of the fglrx code. There's third-party code included. It if where that easy we had seen at least some code copied and adjusted from fglrx to rX00g.
bridgman, correct me if I'm wrong, but didn't you tell that the fglrx team is not allowed to show you any code?
