As a layperson who doesn't understand psychology but is interested in science and peace, I felt that Ferguson's article (this HN post) was much less directed at a person (as opposed to the person's work or theories put forward) and more professional, versus the linked blog post -- so I tend to believe the former.
Even a simple sentence like, "Ferguson did both of these things and his findings thus do not “undermine” our causal claims; he failed to accurately test our causal claims," comes across as scathing compared to the paper.
