Except that this isn't the first game that has advertised this feature. Other games like Mass Effect say that character actions and choices affect the story and it actually does in a major way. Even low budget games that claim this feature have multiple endings and choices that change where the player goes, what he/she does, etc.
If gamers and the gaming industry hear that a game adjusts to your gameplay and that your choices affect the story, they naturally and correctly think that two players games can vary greatly in both the story and actions. Because that is what this feature has always meant.
You can't say "This game has hundreds of different vehicles that you can drive" and then come out with a game that only has two models of vehicles but are in hundreds of colors. Technically you're advertising wasn't lying, but everyone will assume that it meant many models and types. Which will lead to massive letdown and anger.
It's borderline scamming people. No decision in this game changes where you go or what you do. No matter what you say or do, you'll still go to Crawford, still lose the boat, still meet the same guy who takes Clem, and still die in the same room.
No one honestly thought that this would be the case before playing the game.
