Who should be sued? Microsoft who produces an application known as "Copilot" which itself contains nobody else's code but Microsoft's? OR the person who USES Copilot, to produce code which contains somebody else's copyrighted code?
Using Copilot is a bit like using a shotgun, can be very illegal depending on what you shoot at. Creating and distributing the app Copilot is like creating and selling a shotgun.
