I wonder if WTBTS has taken a calculated gamble in publishing this.
On one hand they MUST be aware of the effect of the internet and just how easy it is to research stuff nowadays - and no doubt they are well aware of JWN and similar sites. They can't ignore that.
On the other hand, maybe they have calculated that by publishing this they will be seen by the 'faithful' (aka 'gullible') to be open to enquiry and research and confident that they will still be seen to have 'The Truth'. Always bearing in mind, of course, the over-riding WTBTS mantra 'You don't need to do research, we've done it for you'.
Or it could, of course, be sabotage by an 'insider' apostate!
(I did notice the 'conditioning' bit in the first sentence about 'deception'. Emotional crutches can be real.)
