From my reading of the conversation over the last few pages, I think there is a discussion about a spectrum more than a binary choice. Mostly because things are rarely black and white. So maybe, without speaking for Chaosmancer, its more about how much input you give your players before making the call.
We get a hint of this on page 145 with Chaosmancers statement;
Here we read that they will make calls as a DM, but for them, seeking input is a needed step. Obviously, this is beyond procedural calls, like asking for a skill check or such,
Now for me, I make the call in the moment, and have that discussion later, in a post session debrief, for that discussion's outcome to be applied to future events. I do this because pacing and momentum of a session are things I value. This seldomly comes up for me though, as I have an extensive session 0 and my players are firmly on the same page 99% of the time.
My questions would be, what level of participation should the players have in any random decision the DM makes? And is it different for rules based decisions and narrative based ones? Furthermore, when do you have those discussions with the players? In a session 0, in a post game, at the moment of the decision, or never?
I think this may be a more productive way to approach the topic than the binary "strawmen" everyone accuses each other of presenting.
