I think with all the child molestation lawsuits the Watchtower Corporation is and has been hit with is the main reason for all the prime property sell off recently. The Silent Lambs protest back in 2001, and the Dateline Prime Time expose probably was the death knell for the Watchtower's hey day in Brooklyn.
Their membership is drying up, young people are leaving in droves, the situation is no doubt far worse than the annually published yearbook figures show and so they ceased it's publication permanently.
And those left remaining are experiencing a huge grab of money from their congregations accounts and now are required to make pledges about how much they can contribute which I think is a last ditch effort by the Governing Body to squeeze more money out of the rank and file Watchtower indoctrinated drones.
I think all this is happening because even those still loyally attending are hearing reports of these tremendous pay out that the Watchtower is making to the victims of their self serving policies that put young ones at great risks so that even the rank and file don't want to contribute to pay court costs and so are withholding giving contributions to a very great extent.
