Well, the author talked about meetings after meetings, slow progress and a huge hierarchy of bosses, and you assumed they are wrong to call it bullshit because "Human nature isn't bullshit, and any endeavor which requires a large number of people to accomplish requires the management of human nature."
As if its inevitable that the "management of human nature" should necessarily take the form the author argued against.
A hierarchy of bosses is not the same thing as Dilbertesque management culture. An organization above a certain size requires managers of managers and meetings. There certainly are bad managers and bad meetings, but it is bad logic to jump from that to a dismissal of management and meetings in general.
