Circare, I think you are correct when you say that criticizing the WTS Corp for acting like a business corporation doesn't make a lot of sense.
The issue I have with them is that they never come across as a business corporation to their members, but rather as God's one true channel through which the Holy Spirit speaks.
Never is it brought out that there are shares of stock or profits or subsidiary businesses, but rather that the WTS is above all that money-grubbing stuff that is engaged in by Christendom. And fools that we were, we believed them.
We believed that all funds were being used for the preaching work. We believed that there was no profit being made on the literature....the "donations" only cover actual printing costs. We decried those who pointed out that the WTS dabbled in commercial enterprises. After all, there were all those Watchtowers and Awakes pointing the finger at churches that DID engage in secular activities.
We are like the betrayed spouse who finally is shown the snapshots and videos of their "faithful" mate who has been engaging in adulterous affairs for years. They said they were faithful, and we believed them.
