I can't imagine that the WTS would be winding down operations. As far as I know, they could not just close up shop and take the money. They'd probably wind up in federal prison if they did that. If they cannot do that, then why would they deliberately sabotage their situation, instead of trying to salvage it? The GB have it pretty good! They live comfortably and are almost worshipped by millions of people who support them with every scrap of cash they have. They get to play Pope in a tax-free environment.
I can't judge how they (JWs in general) are doing, because in my area I don't ever see them. I know there are some KHs around here, but I almost never am in those areas and could not say how they are doing. I will say this: I've lived out here almost exactly nine years, and JWs knocked on my door once. ONCE. Never seen a cart, never seen a flyer, nothing. You could forgive people out here for not knowing that they exist.
