But the question realistically is, is it the developers responsibility because they are the ones creating the program. It's not like copilot made you use the code, copilot didn't commit or release the app with the code. Copilot didn't breach the copyright, you did. It's a tool. You used it. You released it. Maybe there's a product which you can include to see what code of yours violates copyright in the future?
