Now if I could just get them to start paying me cash for training their AI on my open source code and selling it rather than being force fed a Copilot grant.
There's no 'open source, but closed to training' software license?
How would you possibly enforce that?
Legally? How else would you enforce it?
Like copyright on training input? Fair use has done a lot heavier of a lift on that than it would every have to do on opensource, license prohibiting it or not.
