What about the emitted code which is actually derived from GPL code? What about BSL, SSPL, or other source available (for your eyes only) licenses? Copilot harvests all public repos, regardless of its license.
IANAL but searched a lot on this, this is very tricky subject legally. To simplify: - imagine all code Copilot trained on is GPL licensed. - we have a universal function `isInfringing(code)` that has access to all GPL code, and returns `true` if it is infringing some GPL code. for a given prompt; if `isInfringing(copilot(prompt))==false` we cannot claim copilot infringing on GPL code, even it is trained on GPLed code…
At what measure is one sufficiently inspired for it to be a derivate work? That is up to courts to decide.
