You can't reform any organization whose foundation is falsehood, whose walls are corruption, and whose mortar includes the wrongful deaths and shattered lives of men, women and children who have been duped into its service.
The only forms of protest that the WTS will ever understand, and the only forms of protest that the WTS specifically attacks, are boycotting Field Service™, Meeting Attendance™ and, most importantly, withdrawal of financial support.
"[L]oyal Christians refuse to believe just any statement made about their brothers, and they certainly do not allow bad publicity" - as opposed to false publicity - "to cause them to miss Christian meetings, to slow down in the field ministry, or to waver in their faith." (Watchtower, 03/01/2003, p. 9, par. 6)
Why do you suppose that there is such vehement pressure on JWs to avoid association with Inactive™ people, or to avoid unnecessary contact with DFd relatives? It's because those are the channels whereby people who have genuine conscientious objections to practices within the WTS can share their justifiable concerns with the people they care about.
