I think what’s going on is that “hard sciences” people in physics etc have a strong feeling that most of economics (and behavioral science and psychology) is bunk, given that economists in particular seem to have all sorts of mutually contradictory theories, are always making predictions that turn out to be wildly wrong, and seem to disagree with one another on basic facts. This paper gives them ammunition to support these feelings that the emperor has no clothes. I am not qualified to judge whether those feelings are correct however.
