> Who can't contribute to Wine?
> Some people cannot contribute to Wine because of potential copyright violation. This would be anyone who has seen Microsoft Windows source code (stolen, under an NDA, disassembled, or otherwise). There are some exceptions for the source code of add-on components (ATL, MFC, msvcrt); see the next question.
I've seen a few MIT/BSD projects that ask people not to contribute if they have seen the equivalent GPL project. It's a problem because Copilot has seen "all" GPL projects.
