I don't think they really are. I think they are annoyed because nobody (who knows the difference) ever claimed that AlphaGo was strong/true/general AI) - and the article feels like it's swatting at strawmen.
I don't understand why so many commenters here are so furious about the author's claim that AlphaGo is not AI. What qualifies as AI is really up to definition, and there doesn't seem to be any widely accepted one among AI researchers. The author of the IEEE article doesn't think AlphaGo matches his definition of AI. Other AI researchers may think otherwise. But that doesn't mean the author is trying to dismiss the achievement of the AlphaGo team.
