I suspect my analysis differs from yours - for one, I read in RNO's request a similar barb: roughly, "You should have included a source when you posted a quote." JGW initial comment noted the presence of this - RNO's - barb, whereupon gwern acknowledged the existence of a disagreement by arguing explicitly for his position. In fact, the first post in his argument is at positive karma - I suspect because it is a valid point, despite being in opposition to the norm.

I would not be so hasty to dismiss JGW's analysis.
