Mods see user behavior patterns inverted - you see comments, they see users who make repeated comments of a certain type.
Good mods eventually curtail some of that behavior for valid but hard to deduce reasons.
I'm guessing that in this case, it's been stopped because user behavior shifts, and people use summaries instead of reading the article.
Edit: it's also generally bad form to have meta discussions, it encourages a form of navel gazing which worsens the signal to noise ratio.
