Because code derived from GPL code is also GPL. Co-pilot (sometimes) intelligently copies and pastes GPL code.

I’m not happy with the Co-Pilot situation either but for the sake of correctness it should it should be pointed out that your point hasn’t actually been tested in court with regards to machine learning. In fact some lawyers have suggested the GPL might not cover that particular scenario.

No one should want to test this - it's terrifying for companies and developers alike.

I think it’s better we do know because that should lead to refinements in licences (eg a GPLv4 that explicitly allows humans to write original works conceptually based off content read but not derived from code from; while explicitly disallowing code use for machine learning except where the published work is also licensed GPL).

It's funny too because GitHub definitely knows the license for every single code sample in their database -- they could easily incorporate this
