A fair criticism, as these questions were submitted by the MCDM community, and most of us play Draw Steel, so the questions are probably biased towards games like Draw Steel.
However, if a GM mostly runs Blades in the Dark as a player-directed experience, and spends way more time collecting music and paintings to set the scene and mood, rather than preparing heist obstacles for their Crew, I'd say that GM runs an art-prep-heavy sandbox game. Such a GM might also prefer to hide enemy factions' plans from the players and blindside them with twists, or roll on the complication table in front of the players and let them see how the mechanics are creating the story. So while I agree with your point, I don't actually find your examples convincing. Perhaps you have experience with games even less like D&D than BitD, and I'm simply too narrow minded to understand your critiques.
