As I posted in the thread that Londo referenced above, I have solid info that the financial changes are internal:
There's a 5 man committee that the borg flys from different bethels in different countries a few times a year and they are the ones behind the financial changes and they have the GB's ear. The idea about the new Kingdom Hall construction funding came from this committee. The main accounting office in Brooklyn has had some lazy habits develop over the years that the GB got wind of, and this was one of several reasons they formed this committee. None of the GB are on this committee.
Now, I can't speak to the other changes but financial/donation arrangement changes there you go.
