Alarm bells went off for me when I was reading under the heading LIE in the Insight volumes. In there it says "true Christians are under no obligation to divulge truthful information to someone who is not entitled to it."
Let that sink in: True Christians are under no obligation to divulge truthful information to someone who is not entitled to it.
They preface that statement by saying malicious lying is unacceptable, but then continue with the thought that it's quite all right to massage the facts in order to keep the WTS out of trouble with Worldly Authorities™. We saw a fair bit of that happening when Geoffrey Jackson was being questioned by the ARC, under oath.
How far does it go? I've seen JWs blow off hard questions from Householders™ in the Door-To-Door™ Ministry™. I've seen people keeping secrets on the basis that the other person "is not entitled" to the truth of a matter (not involving confidential legal or medical stuff, just lying about mundane stuff to someone else so there would be no awkwardness for them for not including the other person in a social activity).
Finally, it occurred to me: This very line in the Publications™ (its predecessor, Aid to Bible Understanding contained the exact same words) gave the GB a lot of leeway in 'not divulging truthful information' to the Rank and File JWs™ in the Publications™, in Talks™ from the Platform™, and in their interpretation of Scripture™. That would account for all the academic dishonesty in the Creation book and other Publications™. JWs would point at the bibliography and automatically think "Wow, look at all the Worldly™ research that backs up our beliefs!" and yet, when someone (Alan Feuerbacher, aka alanf) decided to do their due diligence and look up the quotes, almost without exception the quotes were misquoted, taken out of context, or completely bastardized to support WT doctrine when the original quote did nothing of the sort. It proves, without a shred of doubt, that the GB doesn't consider its own die-hard followers to be "entitled to" the truth.
When that thought crystallized in my mind, the whole house of cards fell apart and I was no longer under their spell. When I've discussed this with on-the-fence JWs, it did the same thing to them.
