From the site:
Therefore, like faithful servants of God in times past, our people feel it is their duty before Jehovah to speak up and speak out when the need arises. As did the Lord Jesus himself, we do not look the other way when we see any injustice done to God's people.
We strongly believe that the religious leaders of Jehovah's Witnesses will receive a heavy judgment from Jehovah if they continue on their present course with regard to these matters. It is time for change. It is our hope and our faith that through the voice of his people, Jehovah will see to it that matters are set straight.
My comment:
There is no such thing as a reform movement in a cult. Even if they succeeded in toppling the powers that be, they in turn would take that position and soon start the same cycle over again. Prophecy would now be interpreted as having been fulfilled in them, etc., etc., ad nauseum.
In fact, I'd say the whole 'Protestant' movement helped create a lot of different cults and that the mother cult is Christianity itself.
TL;DR Successful cults are successful.
