Sorry, but I think that the answer is simpler than planning for specific change. Look, these frauds have lost manpower and employees who might have been able to handle the deluge of Witnesses sending in questions.
Take a good look at the Questions From Readers in the Watchtower and take note that it's repeated, regurgitated, cut 'n paste repetition. These guys are hitting softballs while Witnesses send in real queries that raise serious issues about their excuse for consistent theology.
They don't want to be bothered, they don't have the manpower and they don't care. And guys, why should they? I wonder if any older heads reason that they wasted tens or HUNDREDS of millions of dollars publishing books defending creation or Bible authenticity when it was all pointless. All they ever needed was to assert that 'we have the 'truth' and ignore all the facts. Blind, ignorant publishers wander into Kingdom Halls, they post growth and all is well. Who cares when people are willing to be so stupid?
Feel free to prove me wrong. I'd rather be mistaken but reality here seems irrelevant.
