GND, I am saying that it highly questionable as to whether it meets the legal standard under intellectual property law to be considered for protection under "creative license". I don't think it does.
If there are any "laws" that have been broken in the leaking of secret WTS material, the place to place legal culpability would be on the one(s) who leaked the material. They are the ones who are in danger of being prosecuted or internally disiplined. Like, for example, if it was a lawyer who had breached confidentiality of his client. Not the ones who picked up WTS material (evidence) in public space and spread it around.
If the WTS wants to prosecute for the distribution of their "protected" material, it would be best if they looked inside rather that out here in the public spaces. And, they need to be aware that their "protection" and wall of internal security does not sit outside of the common law of the land. Australia proved that to us.
