That confused me at first, so just to elaborate for anyone else - the moderation team is stepping down, having grievances including an unaccountable core team. Steve Klabnik is on the latter, not the former, so not resigning.
So unless GP is suggesting that the moderation team felt SK's post airing grievances with Amazon was against CoC/whatever standards they expected of him, not related.
I can imagine friction over this piece causing conflict between members of the core team. It could also be that Amazon tried to respond to SK's piece in ways that were against the CoC.

(Edit: oh, perhaps tangentially related after all. See codys' comment https://news.ycombinator.com/item?id=29307113)
