> Let's try the opposite. Say someone got Wine working to the point where it was very nearly, perfectly indistiguishable from Windows and they put up a blog post saying "Everything works just as it should under Windows, because it is Windows." Microsoft's lawyers would come around with a C&D, and calling them pedants wouldn't invalidate their case. Except that isn't the opposite, it's an entirely different situation. 1) It isn't Windows. It's a complete rewrite of the Windows API's. That is not the same thing that's happening here. 2) A C&D isn't a case, it's a piece of paper (politely) asking you to do something. Calling something Windows and it actually being an infringement on Windows patents are entirely different issues. > Precision matters. In carefully crafted theoretical situations feigning as analogies to this situation? Sure. In the real world? Hardly.
