It would have been simple (in my viewpoint) to just charge sales tax to the publisher witnesses who bought the literature at the KH magazine room.
Every other business in the USA, including many "Christian" book stores, charges sales tax.
Now they have to struggle to get enough funds coming in to pay for printing the stuff.
I would not be surprised if they thought up some "new light" about how good witnesses should vow to tithe a percentage of their income to the WTBTS.
But - back to your original topic - what is really rotten about the Watchtower message is that it has far exceeded its "shelf life" - they are painted into the corner of obvious false prophecy and the "end of the world" message has begun to reek as badly as the Camping nonsense.
