Thank you for your suggestion! I believe I can't just edit the article now, since that would be disingenuous, but I'll try to avoid sarcasm in the future and use something like you suggested instead.
You could edit the article in a week or two, once things are calmer (maybe leave the original text in crossed-out form, or a link to the original via archive.org); it might help future readers who don't get there via this controversy.
