The money isn't the primary loss. They can easily afford 28 million toilet papers, since they swindle it from the masses.
However, they are sure to lose because of embarrassment. People in the territory will no longer invite the witlesses in, as if they did after the 2007 NBC embarrassment (the one the day before Thanksgiving). This time, it is in the newspapers, including the big ones. Anyone that depends on mainstream media (print or online) for their news will see it, and it should sit in the dentists or doctors waiting area. The NBC embarrassment was either you were there or you missed it.
The result should be a nice drop in return visits and placements, with a corresponding drop in donations. Witlesses will be hounded to make up the difference out of their own pockets, but they will be less able to get jobs if they have this on their records. Being associated with a criminal organization is not going to help with finding work. Many will get the cops called on them in the territory where before, it would simply be "Not interested". Unfortunately, there are always going to be a few that will be loyal to the bitter end and keep wasting their limited resources for this criminal organization. Hopefully, however, their donations will be down drastically. And that, along with the ability to keep a congregation obedient to something that blatantly doesn't work, will screw them up totally.
