Let me ask some questions.
1. You have written: "When "The Society" made its move and set up the "Christian Congregations of Jehovah's Witnesses", it was the beginning of the attempt to make the religion self-sufficient." In fact, WTS NY and WTS Pa was already recognized as churches/religious organizations. So, should your words be read as "it was the beginning of the attempt to make the third (quasi) separate religious entity self-sufficient"?
2.
When the CCJW became semi-independent in 2000/1, they no longer could show the revenue sources that the WTS has had coming in for those decades (and not all of it was donations). At that time, they had to establish their own revenue stream.
Are you sure? Can you substantiate this claim?
3. You also have written that the aim of alleged funding change was to retain "their" tax free status. Do you mean WTS's or CCJW's tax exemption?
