I disagree. Sorry to be so blunt, but I think your reasoning is flawed, and is influenced by witness residual thinking.
The society has created that kind of thinking in witnesses.
They have said that the only reason witnesses leave, is because THEY have done something wrong. That the BLAME lies with that PERSON. They must be spiritually weak, or a secret sinner, or something like that. (see the "return to Jehovah" brochure for example)
The reality is MANY leave because they see the false teachings, and the high-control tactics for what they are - wrong. They see that there is no way that this one organization has the 'TRUTH' as a result of being the ' only channel God is using to communicate with humans'
Most who leave are more moral, and more honest.
It is precisely because we value truth, honesty,and transparency that we have left the society.
