What I can see wts do is equate faders with DA people, through passing a policy for elders to persuade faders to return and become active otherwise through not preaching the faders no longer view themselves as "witnesses" of Jehovah. After all, they've stated in the past that witness is someone who preaches and successful faders obviously don't thus they can reason they should be treated same as DA. I see wts becoming more cultish than loosing their hold on the people.
Only way I see them loosening their grip on r&f is if they want to sell more khs after more people stop attending meetings.
