The Watchtower does not have exclusivity on being an arsehole organization.
There is no better way to hurt any corporation than by the public learning the truth about them. In commerce people say it by how they spend dollars, in politics it's by voting. With religion its by walking out or slamming doors.
The way to go is the media, there is no point in an attack on HQ itself. The media will, if provided with accurate information, do it for us. Thay will not lead to the Watchtower getting shut down but they may well force them to change like it or not. And if not, then it will stop them growing.
