The GitHub ToS only applies a blanket license to copy as a fallback if you forget to stick a license file in your code - i.e. it's there so that if you post code to GitHub you can't sue GitHub for doing the thing you told it to do. Furthermore, that only covers stuff intentionally uploaded to GitHub by the author; people mirroring repos hosted elsewhere do not have the legal capacity to license attribution-free, copyleft-free AI training.
