The GB are consolidating the org. into a streamlined, low cost undertaking because it makes sense, not necessarily because numbers are dropping.
I speak to old friends still in and I have responses ranging from those that agree with me, but still remain in, to those that now refuse to speak to me even though I am not DF'd, marked or disassociated.
Some people haven't even thought about the overlapping generation stuff, let alone all the other changes and scandals over the last decade and if they have, they find a way to reconcile it.
The same old catch phrases, Trust in Jehovah, Wait on Jehovah etc.
The Gb has simply made it too inconvenient for the average JW to leave, it is primarily for social/ family reasons most JW's stay.
