Agree to disagree for the same reason the guidelines don't say anything about citing claims in comments: What you're looking for where claims are cited for a full background is provided, is not the only valid way to write something worthwhile on the internet.

You insist this piece should be in the form of a cited and fully explanatory journalistic article when writing such a blog post signals no such goal. The intent here is to alert for support, not to be a news source about the topic. Adding the news piece is great for the conversation here, it's just dunking on the post for not being that type of piece itself is overly dismissive.
