I don't think YK is saying the WTS cares about him. I think he believes they would never DF someone for pointing out their hypocritical stand on the UN. For maybe he thinks that the WTS would be afraid that the person who was then DFed might talk to the press about why they were DFed and then end up drawing much public attention to the UN NGO thing. Something the WT would prefer not to happen.
The problem for YK is that the WTS has DFed good people for disagreeing with them on far less important matters. The fact that they would allow someone to get away with a "greater sin" simply to avoid looking like the hypocrites YK now recognizes them to be, should cause him to realize that the WT Society is not now and never has been anything more than a bunch of con men. Why he so desperately clings to his fantasy that they have ever been anything else, I'm not sure. Probably for the same reasons as most JWs who learn the truth about "the truth" I would guess. He does not want to lose his family, his friends, his glorious position in the congregation, or he believes one of the Society's biggest lies, that all who leave them behind are doomed to live a life away from God and Christ.
