I repeated the commenter's own words back to them, showing the irony that they (the commenter) were the one who omitted information, in a way that is very difficult to explain if they had read the article. I think that's legitimate.

It's easy to explain: people remember completely different things in the articles they read, based on their pre-existing feelings and assumptions—just like we see very different things in the world in general. When your feelings and assumptions aren't the same, it's too easy to jump to conclusions about other people, especially online, where we have so little information to go on, and inevitably make up stories about each other to fill in the blanks. (Not talking about you personally—we all do this.) Because these effects lead to stuck, repetitive, and ultimately nasty discussion, the site guidelines try to mitigate them, and commenters here need to follow those.
My working hypothesis is that the commenter probably only skimmed the article, if that. But the really unforgivable part is that that incorrect comment was then voted to the top of the thread. It looks like a lot of people are voting before reading the article.
I'll keep within your guidelines, but my intention was just to point out the irony of the commenter falsely accusing the interviewee of doing something that the commenter themselves was doing.
