The GB themselves have little to no direct control over anything.
How anyone can watch all those internal videos and still conclude that the GB are “not really in charge” is beyond me. The GB micromanage things to an amazing degree, even the accounts department, and planning, things they clearly know nothing about, yet people in the various departments still follow orders from the GB, because they are the spiritual leaders.
As for the OP, I think it is possible that others in the organisation may want to take over control. Who could look at the mess the GB have made and NOT think that it could be done better?
