All the revisions I saw said something along the lines of "this appears to have been an error", which it clearly was. Did someone change it to something accusing the author of acting in bad faith (or even just recklessly) at some point? That said, I think commenting on a error that you last saw a year or two ago without checking that it still exists is pretty reckless (although perhaps that's recklessness on the part of the editor, rather than the journalist, there's no way for me to know - although if I were a journalist I would make sure I read the final version of anything that was going to have my name attached before it went to print).
