So, I can't see how they can argue that the code generated is not a derrivative of at least some of the code that it was trained on, and therefore encumbered by a complicated, and for anyone other than GitHub, impossible to disentangle, copyright claims. If they haven't even been careful to only use software under one license that does not require the original author to be attributed, then I don't see how it can even be legal for them to be running the service.

All that said, I'm not confident that anyone will stop them in court anyway. This hasn't tenmded to be very easy when companies infringe other open source code copyright terms.

Until it is cleared up though, it would seem extremely unwise for anyone to use any code from it.
