I am not fully across the "Ransom" issues that plagued the early Bible Students, but I believe that Henninges defected over this issue, and I think that the Ransom might have been one issue that caused people to defect from Rutherford. He did make many fundamental changes from CTR's teachings that caused most to leave the WTS during the 1920s.
Did Franz revert to Rusell's teachings? Is the WTS shifting its position again?
Apart from these generalisations and unanswered question, I am unable to comment.
