Except for the fact that they haven’t falsely advertised anything. They haven’t lied about any of the visuals, mechanics, etc. Hell they are straight up telling you what features will or will not be in the game before launch.
Don’t pretend that people pre-ordered thinking they were going to get anything other than what was in the trailers.
Unlike food poisoning you can literally decide before using the product on whether you want it.
Just cancel your pre-order if you don’t like what the current state of the game will be. (I generally disapprove of preorders before reviews/gameplay anyway)
