Even so, it only mentions the equipment. Would owning the equipment grant the store ownership over all the information on the computer? Does the store gain legal authority to share that information with a third party that is neither a government official nor a journalist like Giuliani?
In my understanding the policy was aimed originally at stopping the spread of photos like in The Fappening hack. But there was nothing hacked here in my understanding.
If I remember right the basis for why that was legal was that there existed an public interests to release the recording of a private conversation to the public, and that the recording equipment were legal property of the recording studio.
Four years later and the lawyers of NBC seem to have been right on that.
I'd give it at best a 50/50 likelihood of being fake, and would hope that a free and liberal society would demand a lot higher confidence than that before they start wantonly censoring things on the internet.
However the authenticity of the documents isn't even relevant to the overall point. If they are fake, there is a crime of fraud. If they are authentic, it is likely a crime to release this information. There also doesn't appear to be any evidence of a crime committed by either Hunter or Joe Biden. Even if a meeting took place, which no one is able to confirm, that alone isn't a crime. That lack of crime would seemingly eliminate this as an example of whistleblowing. The end result is that it appears that a crime was committed just to make Biden look bad and try to turn the election in Trumps favor. I don't know why Twitter or Facebook need to allow their platforms to be a pawn in that game.

Except, if it did take place, Joe would be caught in another big lie because he stated he never had any dealing with Hunter's business.
