I agree that we shouldn't shoot the messenger. It's good to hear what kind of rumors are circulating among the Witnesses.
I think it's easy for Witnesses to mistake sending take down notices with significant legal action. What I find remarkable is that they seem to have stopped sending these notices. Their first round just caused more videos to be uploaded including parodies and videos with commentaries. If they do a Scientology like attack, I think they realise it can backfire greatly, with a lot of unwanted press coverage. They may occassionally send a take down notice for videos that reach a certain amount of views, but I think they are smart enough to not do more than that.
