I did not leave because of the hypocrisy.... but I dared to begin a careful examination due to the lack of love and hypocrisy. Such a shortfall of Love, that I began to doubt that God could be involved with them at all. [In fact, not much different than the way I view most churches that claim an exclusive relationship with God nowadays.]
I found an organization that had lied to it's people and called it 'new light', that had hidden agendas, had violated it's very own moral codes on many levels, had misrepresented itself, misrepresented prophecy, in fact altered the Bible itself to support 'the unique teachings of Jehovah's Witnesses'. Now those were good reasons to take a healthy look. Once one does that, it becomes apparent that the membership is just a bunch of deluded people - and yes they are imperfect - but never did that drive me to leave. In fact I overlooked that for 48 years. I still do.
I actually don't see much of what you state that you see: People claiming to leave over imperfection of the individual Jw's? In fact, in four years on this forum, I don't recall a single time that I ever saw that stated as the driving reason that someone left. Could you please point out where you have seen it? After leaving, the level of resentment that some have felt over decades of deception might lead them to a phase of criticism of Jw's as people, but most seem to recognise that Jw's are good people, mislead by an evil organization.

Edited to add: Although I did not leave due to imperfection - I did believe that Jw's, as God's people, had an obligation to act in a fashion that would represent Him. Failure in that regard did provide a significant part of the 'spark' that ignited the fire. But if the organization had not been combustible in that investigation, I would have remained and continued my tolerance of the imperfect people. All people are imperfect.
