Smiddy, I do not know when it started, but in past two years I hear complains from my JW family that WT needs more money and donations. My mom often points out that 20 years ago nobody asked her; but back then we had donated a lot of money so we can build our first KH, which was build from our local contributions. Since my mom contributes for decades and surely every week when she is on program, she felt it insulted when elderette asked her why she puts only 100 crowns (which is the smallest paper bill) when she could afford to put more. All my JW relatives who are in different congregations complained that the donations are demanded and required instead of a time, when they were voluntary as I remember. I left the cult in April of 1994, so I do know only the religion who was at that time, which surely evolved into organized group with well paid priesthood.
I think the money is the biggest reason behind awakening of both of my sibling and my mom, instead flip flopping doctrines, and all other BS with JW religion. At least both of them feel that WT is not right on this. Money is something that people relate to it more on personal level,than 7 times of 360 nonsense and parousia, and this shakes more in their beliefs than all other nonsense.
