Ironically, in today's WT, JWs are encouraged to study the early history of the "earthly organization".
Like them [the sons of Korah], do you have a desire to study and recount the history of the earthly part of Jehovah’s organization? The more you learn about God’s organization and how Jehovah supports his people, the more real God’s Kingdom will be to you. -- w2012 8/15, p. 12, para. 5 - [Emphasis added]
Imagine if all the JWs really did that! It would cause a nightmare of trouble for the GB.
I can only guess they know that most won't bother, and of the few that do, the majority of them will only study the WTBTS's sanitized versions of their history. The remaining ones that actually learn the factual truth about the early history of the organization will all become apostates.
Interesting gambit in the propaganda techniques of the GB, oh, excuse me, "The Faithful and Discreet Slave!" I guess it's a chance their willing to take to appear open and honest. The few that will leave are all trouble-makers anyways!
