“Selected congregations” will experience these changes, first anyway.
Its put out there as a taxation issue. It could have something to do with Watchtowers charity status, also could be something to do with hiding Watchtowers money at certain congregations so that it is off the official -getting their arses sued off- books.
I suspect that Watchtower will be transferring their wealth to “selected congregations” under the control of devout COs, so that when they lose the lawsuit, they can pull out their rabbit ears.
