I think the video answers the question as to whether or not the GB are competent persons to be in charge of a multi-national corporation.
I don't think it addresses the question of if they know what they are doing concerning the shoring up of a religion that is unsustainable in the long term. In this case I believe they do know what they are doing. They know that the only way of keeping people in is to press all the right emotional triggers around fear, obligation and guilt. They might be spinning it differently in their own heads but they know they cannot keep doing it the old way.
All they have to do is make the majority feel the right way and then cognitive dissonance and the sunk cost fallacy does the rest for them.
