They risk losing some members by increasing this type of swindling.
I know of cases here where donations were taken for the WWW... it adds up to millions $ stolen from Australian congregations who were expecting to get KHs built, and that’s just the few I’ve heard of locally.
Mention the fire sale and JWs always reply with “there is massive growth in Africa! They NEED the KH more in Africa ...”
The WTS must have multi-million dollar investment plans for a massive African continent expansion. Given the extent of the recent sales, it could be in excess of 1 billion dollars. The WTS might invest so much money, they will single handedly pull nations out of poverty, feed and clothe entire villages and stem the flow corruption!... or they could pay lawyers vast sums of money to defend the WTS against accusations of child sex abuse.
Probably the latter, sorry Africa.
