I'm guessing that the view by people here is that the NYTimes took an the Article and published it standalone, by itself, as they would one of their owns, without attribution.

The NYT wrote an article, referenced the one in the PDF, and provided a copy of the PDF (of an old black/white scan) as context/background.
