I think their use of that paper is a bit sloppy, but you're sort of doing a similar thing by making a strong rhetorical claim "This author does what other pro-industry mouthpieces do" while ignoring the point of the paragraph, "Richer countries have near-universal refuse collection and almost none of their waste winds up in the ocean", which is broadly true[1]. North America and Europe account for 5.1% or ocean plastic. India alone accounts for nearly 13%, and the Philippines nearly 37%.
