I read about a situation that might compare to the Borg going bankrupt. What happens when a church goes bankrupt
It could be done to reduce a huge payment. Each country has laws regarding what is legal in it's jurisdiction. In Singapore some church officers got convicted of "Breach of Trust" for mismanaging money and could happen also. The Kingdom Halls are not assets that they can sell directly so closing branches and selling other real estate is something they can do.
The Society have smart lawyers and probably have structured themselves that they can survive any "attack" and have conditioned the faithful to listen to them no matter what. Rutherford was in prison along with his associates and that didn't deter him. Bankruptcy and other such problems won't deter them either. They will lead and there will be those who are willing to follow because people like the fantasy of living forever and never dying, of growing younger and healthier instead of older and no other religion is offering that.
