You really seem to be ignoring the core issue by focusing on SO though. Everything on SO is fair game, but code on GitHub is under a variety of licenses, and when Copilot regurgitates it, no matter how complex and inscrutable the process is that leads it to do so, it may be causing the user of Copilot to misuse that code because it doesn't even give them the opportunity to know where it came from or what license it was released to the public under.
