(1) Your comment suggests (even if you didn't explicitly state it) that the author hasn't taken more than 1 undergrad physics course. However, the author has a doctorate in chemical physics, and have written textbooks on physics that are published by Oxford university press. It's highly unlikely that he haven't taken any class in physics.

(2) If you didn't meant to suggest that the author is just a "wanna be philosopher of science" with no science education, then the sudden call for (even if hyperbolic) ban on phil majors has no relevance to OP.

(3) Moreover your comment also suggest that phil. majors are somehow the problem in some unique sense (why not ask for banning anyone who haven't taken a QM course from talking about QM). But you provided no example whatsoever of phil. majors in general (discounting one or two possible exceptions) causing ruckus spreading misinformation on QM. So it's not clear if you are even thinking of phil. majors or just random people in internet who engage in philosophy and QM (without being educated in either).

Your comment, thus, seems like either making unwarranted suggestions (that could have been easily fact-checked as /u/tiredstars suggested) or completely orthogonal to the OP article and its author.
