GPL folks are completely OK with something like Copylot when GPL license is obeyed, so all emitted code, generated by AI trained on GPL code, is licensed under GPL again. It's not OK to call our code as «public code» and ignore our license.
But by repeating this argument you are strengthening copyright, which is the fundamental evil GPL was made to fight. There surely will be FOSS clones of Copilot in the near future. There is no need to feed the copyright lobby.
