The more I see what Watchtower leadership does, the more I think doctrine matters less and less. It used to be you had all these people in leadership positions constantly pondering the big questions. Watchtower articles routinely delved into complicated explanations of doctrine. The average member could explain the significance of all important dates and what it meant for worship in the 20th century. But now, as organizational trust evaporates and social media proliferates throughout members' lives, all emphasis from leadership is on behavior control.
I don't think faith matters much anymore. As repeatedly drilled into the flock, the GB just want obedience. If you disagree, that's okay, as long as you still do what they say. As in a child-parent relationship, this would seem to be a healthier arrangement, but it undermines the locus of control that the Watchtower has historically exercised: belief. By relenquishing control over the beliefs of the rank and file, they shoot themselves in the foot. Rebellion is only one step away.
