I am wondering if release of confidential information such that it appears in official court documents carries enough weight as to be able to impact other legal proceedings that may arise totally unrelated to this case. In other words it's one thing for $1 billion to appear in news articles (and be widely know) and another thing for it to appear in a court transcript which could then be cited as proof that the number is correct and used against the party that didn't want it disclosed (in a way that a news article can't). Often in negotiation there is bluffing. It's easy to bluff around non-official information is what I am thinking.
