The article ends with the statement "The author declares no competing interests". I think this is very poor phrasing, as it's ambiguous: does it mean "The author has not declared any competing interests", or "The author has positively declared that there are no competing interests"?
(To be clear, I am not for a moment suggesting any hidden interests on the part of the author, and I think his point is both correct and important. It's only the wording that I dislike.)
