I believe this is the point of the strategy. Imagine the presenter is hired in as a consultant, but the audience are the ones footing the bill without any knowledge of the actual work, timeline, etc. involved.

All they want is a white dude in a shirt, tie and suit to talk a lot and sound smart. The easier it is to convince the audience of that, the more suitable to purpose the presentation is.
