The article doesn't quite make that point. You can say one thing (you didn't account for time, money and staffing), or another (great plan, I hope we can find the time, money, and staff), and get the same strategic result. What you don't do is notify people of the root cause - the manager who thinks that time, money, and staff don't need to be accounted for. The question is - what are your goals? Making the presenter look bad is only a good idea if you are in a culture where all bad ideas are attacked (hopefully without cramping innovation), or you are pretty sure the presenter needs to be taught a lesson. But otherwise, it's better to achieve one goal without the other.
