With internet access to material published by the Watchtower and it being offered free door to door and at the congregation literature counter it should not be surprising that the WTB&TS doesn't make the same profit as before when literature had to be paid for.
So the nonprofit corporation must turn to other sources of income, like playing bank with the congregation's money, as well as selling property of which they have a sizable fortune. Beg for more money from the mostly poor rank and file, suggest willing leaving valueble property to the corporation, mandatory tithing, and etc...
Part of this sellable property are Kingdumb Halls owned by incorporated congregations which thier by-laws give the WT complete control. As times get worse for this corporations I would expect them to be tapping this source of revenue more frequently.
They are selling all their Brooklyn buildings, and closing down branches and selling the property, and they are selling Kingdom Halls(who gets the money?).
