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.
I think that it's a combination of factors. The sexual abuse scandals raise awareness to the general public, but they have quite a few more issues to deal with, mostly consequential of their ridiculous business practices. Yes, the sexual abuse scandals puts them in a bad light to the general public, but they themselves are not exactly the most savvy people when it comes to properly running an organization. That is harming them too.
