it's hard to see Microsoft's operating system competitors taking advantage of it. Wine. If I was them, I wouldn't be interested in copying it, but I would be interested in seeing how things were actually done (to confirm inferences as well as resolving puzzles.) But I believe that even seeing code leaves you open to a copyright infringement suit, which is why people do clean room reverse engineering. So, I wouldn't even look at it if I was them - despite my interest :-(.
