I think the WTS is trying to use copyright law in these cases, where they are accusing people (like McFree) of using material without express permission. The law (at least in the USA) almost always sides with the person using the material unless the use meets certain criteria. What the WTS wants is to intimidate people into removing videos or documents without proceeding to a court of law. This works frequently because those people do not have the resources to fight back. When they do, the WTS usually loses the case and/or (as in the McFree case) drop it.
They also try to get personal info on the people uploading content if they think the person is an active JW (as McFree is, if I am not mistaken). Then they can disfellowship them. McFree's lawyer pointed out that the WTS is not interested in pursuing copyright claims as much as they are seeking personal info to punish those who speak out against them. Once they have the personal info, they usually do not pursue the copyright claims any further. This is, effectively, a misuse of the legal system.
