Except one that hides to the users the source they are copying, helping them to violate any open-source license that requires proper attribution and, what's worse, any #copyleft imposing reciprocity https://video.twimg.com/tweet_video/E5R5lsfXoAQDRkE.mp4
That's why I wrote the #HackingLicense http://www.tesio.it/documents/HACK.txt so that when we will be able to prove that #Copilot distributed any work under such license, we will have to assume that #Microsoft accepted the license, that the "models" of #CopyALot are used under its terms and thus all the software that adopted its "suggestions" can be used under its terms too.
