It may never happen, I believe the best that can be hoped for is to pull some people out of it. No matter what is found out, no matter how big the screw up or lawsuit or lie that is uncovered, there will always be some who believe. Selling hope is a big business, and some people want hope way more than they want truth.
The blood expose', however, is great in that it gets more information out there to a large audience, which will eventually cause the WTS to go into damage control mode, changing policies again. The good thing is there will be some who begin to think a little for themselves when they see the change, but in a few years, it will have blown over and most of the people that are going to come out over the change will be out, with those remaining calling them apostates, weak in the faih, etc, i.e. the UN scandal, changing the understanding of "generation".
Does that mean this news is less importaint than hyped to be? No, I think it is great that there is something out there that will bring the issues back to the surface, and possibly pull some more great people out of an organization that turns them into victims.
So, I think the WTS will always exist, they are excellent and damage/mind control, and will adapt to anything that is found, period. The people who uncover the truth will always be lying apostates, and the remainder of "The 144,000" will never die off. This is their business, selling hope, and they are damn good at it. The hope is for the few that get out, I'm glad the cycle continues, I was pulled out of my hell because of it, and it's great to know that there is potential for anther significant exodus.
Big News indeed!
