In the beginning, I will believe that if you are deceived then you will not believe or say that you will be more cautious. White papers can also be imitated. All things can be spent to make you believe that it is true. All can't just look at the white paper.
The white paper itself normally contains a large disclaimer. I have seen one that is 20 pages long. Most of them simply tell you that the team has no obligation to follow it.
