How do you know it was a Watchtower representative who complained?
According to the latest Click programme on BBC youtube are very quick to remove videos and whole accounts following complaints. They do not bother to verify that copyright has been infringed or that the complainant represents the copyright holder.

With that system for dealing with complaints it is remarkable that independent Watchtower vigilantes have not been getting a lot more anti-Watchtower videos removed on the basis of dubious copyright claims.
Apart from all of which, I do have to wonder if in fact V did breach strict copyright rules with a recent video I saw. He seemed to acknowledge he was sailing close to the wind, or at least invite differing opinions, by highlighting the whole copyright issue in the video itself. Which is a bit of a shame because the content of the videos are good, and would not be much diminished by steering clear of any possible borderline copyright issues.
