So the hypothetical situation is this: You get a letter from party X asking you to do Y or suffer consequence Z. It seems to me that if the threat of consequence Z is really sound, X will not mind if you publish the letter on the Internet or take out billboards to share it. Whereas if they want it kept secret, they must have something to hide, such as the weakness of their position. Mind you, INAL, so I am merely musing aloud for entertainment purposes only.
