This is my opinion based on what Ive seen and come to know. Its all about the system or machine at this point!
Knor perfected a machine that rutherford created (I believe that russel started an Idea that rutherford turned into a movement.) Knorr fashioned a system that could carry on in perpetuity (sp and trying to use big words) Even with franz crackpot ideas knor made sure that the system itself would continue. Look at his moves to reduce the power of president after he died and the creation of the governing body to share power and decisions.
Now I feel the system is firmly in the hands (and guidance) of the law department. Thus we see the changes to get the GB off the rulling boards and isolated from the corporation.
