Seems like another CYA move.
If they ever print something that could lead to a lawsuit, who do you sue? In the past, well, it was printed by the "Wathctower Bible and Tract Society", a real corporation operating under NY or Pennsylvania corporate law.
Now - who do you sue? "Jehovah's Witnesses"? What exactly is that? How exactly do I sue "Jehovah's Witnesses"? Can I sue "fast food restaurants", or "car manufacturers"? No, I need a specific target.
A religion run by lawyers - is there a more frightening entity that you can imagine?
