I agree with the opening post that the Internet has by far been the best weapon against the growth of the Jehovah's Witnesses cult. It hasn't been just one thing exposed , especially since 1995. Not only the overlapping generation fiasco, it's been everything : the Australia commission on child abuse within the WT Society, the Candace Conti child abuse case which received a lot of mainstream media attention, the no-blood transfusion deaths which are getting more publicity in media these days, and the extreme control measures put upon rank & file JW members to " trust " the WT organization - even though they don't understand what the organization is saying. The selling off of kingdom halls making it more difficult for JW's to travel 30 minutes or an hour more to meetings. It's a combination of all of these things that starts making a JW doubt. Lack of real love , etc. Any one of these things can put a seed of doubt in a JW's mind until they get to their breaking point and have to leave.
That's how it happened with me, I reached my breaking point in order to get my freedom and happiness
