We are all having fun ripping the WT Society for money grubbing, but it is not much different than what they have been doing the last 20 years, and in some ways better.
Before: WT's RBC says a Kingdom Hall needs upgrades (maybe it does, maybe it doesn't). The work is done by unpaid volunteers, with donated funds. The local congregation takes on a big monthly payment for years to 'pay' for it. The WT uses this as an income stream, in fact it is probably their biggest single source of income, at least in the developed countries. It was really a scam and in some ways a deception.
Now: It is all donations (maybe not exactly freely given, as there is some implied pressure). At least they are not hiding the income stream making people think they are paying for the renovations.
I still have a suspicion that there is a legal reason for what they are doing which hasn't come out yet.
