The ex JW community is a diverse group with diverse goals. There is no single entity with a single goal and therefore it is a falcious argument to compare all of us with an organisation.
The question also assumes that the JW organisation has been successful. I would argue that whilst it is accomplished at controlling the flock and raising money it is less successful at looking after the flock and preparing them for life. It keeps it members so closely contolled that they are emotional and social outcasts unable to care for themselves financially. They have successfully brought misery to families by putting loyalty to themselves ahead of family relationships. As a religion it has a responsibility to make life better for it's adherants and be a source of spiritual refreshment in the wider world. I cannot see how this has been accomplished by them so no they have not been successful.
What I can say from my personnal experience of the ex JW community is that we appreciate what it means to exit this cult and do try to support one another. What is lovely is that people can hold diverse opinions and these can be challenged. The ex JW community is more successful than the organisation in freeing the person to think, challenge and disagree with others, to be prepared to debate and present evidence. There is much appreciation for others here, sometimes some intolerance but we are able to work it out after all it is a shock to discover an ego and a sense of self.
I am truly sorry for the OP I hope that the responses here help them to reflect on their very judgemental conclusions.
