Even if the WT should be forced out of business because of the pedophile problems, or because of having to file for bankruptcy, or whatever the reason, they would soon be back in business again under a different name. Perhaps some other super, uber JW would take it upon himself to reopen the franchise.
It has happened before. When CT Russell died and Rutherford took over, his vision of the WT was completely different from Russell's. The name WATCHTOWER was just about the only thing that was retained.
And, there will always be loyal followers that will go along with whatever changes are made, whether in doctrine, financially, or whatever.
As for what those changes will be, it is almost impossible to predict. Just when you think that you have WT figured out, they make some radical change that no one saw coming.
