I agree. This editor may well have been a current-day culmination of a trend that started some time ago. I stopped my own print subscription to SciAm once the articles started to ostensibly push certain sociopolitical viewpoints in the guise of science journalism. This was well before the editor being discussed was editor enough so I never knew this person existed.

While this editor may have crossed some redlines, I am doubtful this change in represents a genuine philosophical shift at the magazine.
