It's dicey according to the GPL FAQ [1]. It goes against what GPL authors want: their work being used in proprietary projects.

This could have been prevented very simply: GitHub avoiding training Copilot on GPL code.

What they can still do is offer a new model excluding GPL code for people who care about it.

They would also have to exclude virtually all code that isn't public domain, too. MIT and Apache-2.0 and BSD all require that the copyright notice and license text is preserved in downstream use.
