Agreed, why is why I really do not like how much people are beating on him, but the problem remains that he published an article with fabricated quotes, which hurts not only his own credibility but that of Ars as a whole. I think that it may be best for everyone if he applies the lessons that he learned at another place of employment.
(Also, though, Ars really needs to do something about its culture regarding working while sick, as that makes it inevitable that a mistake like this is going to be made, AI or not.)
