Huh? The 2024 DMG, which I quoted previously in the thread, instructs DM's to prepare an adventure by writing down plot points. That is, the adventure is to be scripted. It also instructs DM's to 'embrace the shared story.'
This is contradictory advice, and therefore bad. You can't let players drive the story and follow a plot.
Then you have this:
In other words: DMs are given license to lie and cheat, but instructed to be discreet about it.
How do these two criticisms interact? In my experience, over decades of play, not to mention the experience of many others, one common way to resolve the contradiction between 'plot points' and 'shared story' is shenanigans. Stuff like arbitrary DCs, outright ignoring things players say, and, of course, fudging the dice. The old Forge jargon for this is 'control'.
It's toxic, unfun, and sanctioned by the book that is supposed to be the official teaching text for dungeon masters.
