" I can see them not wanting the R&F exploring all the details."
Especially if they were to find a copy of Rutherford's letters to Hitler where he assures him they are not a threat, but the Jews are ! Carrying on a blatant Antisemitic trope. And if the JW's then find out the truth about how the poor Bible Students who had bravely stood up against the Nazis and gone to Concentration Camps felt about Rutherford's actions.
They felt Rutherford had betrayed them, and betrayed what they stood for, being "no part of the World". And so a large number left the Watchtower Org in disgust and loathing, but J.W's were told in the JW Org publications the huge LIE that these Brothers and Sisters left because of " Materialism" !!!!
Oh yes, there is a lot the JW Org do not want their adherents to find out !
