I think overall, like the Titanic, organizational dissolution and Bethel cancelling its own ministry in the process is what may get through to some of the mass JW herd. And since the world system has to run its course in that aftermath JWs will start to percieve what went wrong and why, imo. When the object of faith in men and org goes down any with that faith will also have a "test of faith", unfortunately in the wrong things which is what Bethel's system has become.
Due to the steady contraction in growth and even possibly concealed contraction in actual JW numbers, gradually Bethel is itself killing the potential numbers by their own policies, so in a way many have finally left as Bethel's fruitage is not a good overall influence. The congregations already have taken on the ice water, but apparently it has been so gradual few care, notice or live in denial that all the worst principles of the Bible, "fulfill" right in JWs.
But JWs are the last victims, when the ship goes down hopefully we treat the JW survivors better then they treated their shunned brothers and sisters. They are partly too blame for condoning the Bethel tyrants, but Bethel is the lead icemen. What JWs can kiss good bye is anything they ever gave to that ship, imo, it will be gone in a matter of a couple years, from the time the "self fulfilling prophecy" begins to activate on the Bethel Titanic.
The GB is the rogue captain that took over the controls in 1976, and that is the experimental management that has fully failed, JWs just do not know it yet. Imo, Bethel ends long before the world system even culminates into final global management systems. The premature end scenario is what keeps many JWs there. If they plainly told JWs the truth, that it goes on a number of more years, many JWs would leave. If the fear magnet was depowered JWs could comfortably abandon ship, but Bethel won't become truthful because they will not take a bite out of their free paycheck.
