The way I see it is that MS has probably put as much financial investment in the development of this product as in the research of legalities regarding its release with its highly paid legal army. To expect a multi billion dollar company to not do its due diligence seems naive.
Maybe this could spark a discussion to change the current rules that allow them to do this, but questioning the current legality to me is a waste of time.
It's a gamble. Worst case they have to reduce the quality by removing GPL code from the training data. And/or pay off a few lawsuits, which is routine stuff for them. Cost of doing business.
