The leaders of the Watchtower or JWorg (GB) as they are known now dont want people within the organization to examine the bible teachings which is being forced upon people at Kingdom Halls etc.
Not surprising mind you since all these men past and present are true apostates against Jesus's teachings and instructions to those wishing to be loyal to him.
The GB men want people to be loyal and subservient to them.
Ironic to the fact that when you become a JWS you instantly become an apostate in Jesus's eyes.
