There are numerous reports of what was said about him in the Congregations. I personally heard how he was at the lead in this apostasy movement. That he was spreading false teachings and that he was only interested in gathering followers for himself and to make money from it.
You are right about the Watchtower not needing to do anything about it. However, I was under the impression that they try to do things in a similar manner to the first Century christians. From the secret JC's to the disfellowshipping of individuals without the Congregation knowing of the 'sin', none of this is similar. Disfellowshipping for having a meal with a df'd person is also unbiblical.
Fisherman - He went public and by doing that he broke the rules that he subscribed to when he joined jw.
What rules are these that he subscribed to when he joined?
