For sure. The bulk of the issue is that a large subset of players don't like the idea that the GM is just "making things up"; they don't want to see any sort of narrative "contrivance". They want to imagine the setting exists outside of the shared playspace at the table.I mean that's essentially what the complaint boils down to. The cook isn't pregenerated and that lack of pregeneration impacts play in these ways, some good and some bad. The complaint obviously focuses on the bad.
Techniques that let the table see the sausage being made, as it were, and that the setting is just the GM imagining things aren't appreciated. The pain of the "quantum cook" is being reminded that the GM is just making stuff up.
