The ONLY possible thing that I can think of is if the Hedge Fund debacle causes governments to reclassify the Watchtower as a profit making organization (Based upon their usage of donor funds to invest the overwhelming bulk of their liquid assets in investment funds). If they are then fined for back taxes it could cause the organization to falter as a formal religion. Imagine the Watchtower filing for chapter 11. LOL.
However informally Jehovah's Witnesses and the doctrine would still continue for many many decades.
