The tone of the responses is commensurate with the tone of your question.

Do you really believe that on this board, if you ask a question the way you did, repeatedly hammering the point home about this, that you should expect anything different than what you got?

If you do, well, I feel sorry for you. A more tempered question might be worded this way:

'I noticed a Mr. Cook was swapped out with Mr. Berman in the Attorney Letter revision - anyone have any insight? Could it be just a typo"?

Instead, you took an accusatory tone...so, you got a response that was on par with your question.
