I think the exposure of the WTBTS/GB would be the greatest thing ever! Sure, some hard-core zealots will be loyal to the cult, but many would leave and never return.
Just think of all the children whose lives have been ruined, or are currently being stolen. Think of all the talent going to waste, all the dreams that are dying, all the lost potential. The best thing that could happen, would be the exposure of the WTBTS as just another man-made cult.
There would be some fall-out, but that's life. The end result would be worth it.
