"The contract of sale contains a confidentiality provision that protects information relating to the buyer and price." Wow that sucks, would have been quite interesting to know how the government found a buyer and how much it was sold for.
What would be the justification for making it private anyway? Shouldn't this be transparent?
If people know who has it, they might try to extort him or worse.
I don’t see any reason the information needs to be public.
