Like the review which allowed them tonignore licenses while ingesting all public repos in GitHub? - And yes, true, T&C allow them to ignore the license, while it is questionable whether all people who uploaded stuff to GitHub had the rights given by T&C (uploading some older project with many contributors to GitHub etc.)
Different threat profile. They don’t have the TOS protection for training data and Microsoft is a juicy target for a huge copyright infringement lawsuit.
