Thanks for the leak.
Watch Tower cannot afford to lose more control than has already slipped away as a result of the global emergency, so the GB must now dictate what is discussed among small neighborhood groups and family groups.
Watch Tower is much too micro-managerial and paranoid to allow neighborhood and family groups to freely "encourage one another" without the discussion agenda being strictly controlled by the GB.
#4 in that letter about restricting JW Stream is a very telling point. Watch Tower cannot permit a single congregation to stream out meeting programs to national audiences of unlimited numbers because it would give that one streaming congregation an unfiltered voice and authority rivaling that of the GB via official JW Broadcast... a potentially mutinous risk that Watch Tower will not tolerate even during the unusual changing times of a global emergency.
Condensed, centralized control is critical to Watch Tower survival because when that centralization deteriorates, JWs will naturally unplug, begin to think for themselves and act independently. Same thing happened to early Christianity as the apostles lost their grip on the congregational groups, and also at JW HQ several times over the decades.
Due to this global pandemic, the future of Watch Tower trajectory now relys heavily on the performance of congregation elders deployed with marching orders to ensure each individual JW home keep minds plugged into the GB control matrix.
