Damn. No. I do not believe that the WTS has protection under the copyright laws.
Their publications don't stand the sniff test.
Firstly, their indoctrination propaganda is "freely" distributed to the public.
Secondly, so are the elder's manuals and letters, etc. A select group of "the public", but the public, nonetheless.
Thirdly, an underlying principle that is part of the establishment of the copyright laws is such that the protection of ownership of "creative material" would stimulate more creative projects/endeavours. That is one of the primary purposes of copyright.
Fourthly, the publication of "fact" is not creative.
Fifthly, the ARC was not blocked from publishing the material to the public.
The WTS material doesn't meet the standard on any of what copyright law requires or is intended to protect.
The WTS is trying to set their own rules and call it "copyright law protection" when in reality, they are dealing with security breaches within their own organization. That's all. That kind of information - secret corportae stuff - is supposed to be kept secure if they don't want people to get their hands on it. That is why it is "secret". They can't legally protect it any other way.
