One thing that people have today that others in past didn't is the inter-net and the available information that can be derived from it. The foundational history of the WTS. from the late 1800's throughout the 20th century is now quite easily obtainable for anyone with a computer and the inter-net.
One thing that can be observed is that the WTS. from its earliest beginnings had its critics coming from all directions and sources some religious and not. When J Rutherford took over the organization this is when the real power structure of the organization started to develop . This self proclaimed pseudo judge grabbed a hold of the organization with all of its containing wealth and power and utilized it for his own self opportunistic personal agenda.
The really deep problem though was at its core doctrines which were founded on false misinformation of construed doctrines, which didn't have any bible support or either outside secular support. So the organization grew itself from exploiting people's ignorance concerning bible interpretation and perhaps appealing to their emotional insecurities .
Nevertheless from out of that beginning power structure the organization developed itself into a broader semblance of power from DO's , CO's Congregational elders and so forth. A pyramid formation of power was created to hold together the organization and rules and regulatory laws were eventually handed down to maintain that power structure.
One of these rules and laws created was the DFing policy on to those that were deemed too problematic and injurious for the organization. people were now being carefully watched closely to their activities and everyone was suppose to watch out (spy) to ones who weren't adjusting themselves to the controlling directives of the top president or GB members .
Gradually there was becoming a very high controlling organization that watched how you were dressed to the length of your hair, to who you associated with, to what you read and what music you listened to. Everything and anyone could be a potential evil spirit trying to attack and weaken your life saving righteous spirituality. To this day most JWS are in a state of fear induced paranoia about most things in their daily lives, in fear of those evil spirits and those evil spirits can be anywhere from other churches to outside community organizations ( ie. Boy and Girl Scouts ) any government institutions or any outside charitable organizations, even your own family members who aren't JWS themselves. The WTS leaders had intensionally devised this to garner direct support for their organization alone in a very selfish self assuming way.
A true and faithful JWS is to talk, look and behave accordingly to the specific design of the top leaders to formulate a outside appealing image around the organization and then stamp their directives as Jehovah's appeasing choice.
That may look good from an outside perspective but inside is where you find all the false conniving and coercive doctrines.
People are being drawn in by disingenuous means and rigidly conformed mostly on provocation, fear and ignorance.
