You clearly didn't read the article closely enough. The first header is "The Numbers Aren’t Working Out." If it was about the audience, they would have switched stopped earlier.
when posts like this get flagged, but posts on the opposite side of the political spectrum don't, it really discourages people from posting. This seems like a valid critique of the content of the article that was posted whether you agree with it or not.
