This is just another example of classic Orwellian doublespeak on the part of the WTBTS and its representatives.
In JW-land "confidentiality" really means: cover-up
That is exactly right.
One evidence of the accuracy of that statement is the fact that elders talk amongst themselves even to other elders in other Halls.
There are guidelines supposedly about "only giving the details necessary" but as we all know, in the strange workings of the inner world of JWism, elders do what they want.
Part of "doing what they want" is the unbridled gossiping" that is done by elders to elders after meetings, at Regional and Circuit and Special Assemblies and on phones late at night.
