To me, it seems obvious (I should say though that this is speculation, even if I think I'm right) that she was fired for precisely what she's doing in the article: looking for sexism where it doesn't exist. You cannot coach that behavior, you'll get labelled sexist immediately. There's no way to correct such a problem before letting someone go.

And providing reasons after the fact, as others have stated, is a bad idea because it opens up liability. You have no discriminatory reasons whatsoever for letting someone go, but you bumble some words and the next thing you know you're getting sued. Better to treat it like you're talking to the cops and just not say anything.
