The article was definitely what brought it to a head because it prompted some people to say publicly they had bad interactions with Rod Vagg.
There were also a number of thoughtful responses to Rod's tweet where people spelled out why they thought his attitude towards CoCs was unhelpful. As far as I know he didn't engage any of these authors, which makes me suspect he was not actually looking for "interesting discussion".
Overall it was inflammatory in the same way another article complaining about missing generics in golang would be inflammatory here. The article doesn't seem to respect existing work and doesn't bring a new or evidence based perspective.
I agree it would be nice if all the complaints, responses, etc were laid out plainly. But I can also understand why this is not the case, given tweets like https://twitter.com/ag_dubs/status/887785046320480256 and the understanding that there's little benefit for the women involved to gain by re-litigate these interactions in public.
