This is a very good point. This is like a negotiation. You don’t have to, nor is it wise to, divulge every thought process and what your decision making process is. You are supposed to obfuscate all of that. You posted so much information in this post and if you were to do that in any letter to the company you’d be given them all the legal cover they would ever need not to mention all of the leverage in the negotiations. You’ve got to be shrewd while negotiating and doing business. Read the parable of the shrewd steward that Jesus told and ask yourself what you think about his actions.
Point taken. My letter will be on a single page and will say as little as possible. I'm getting Freepmails advising the same thing.
Useful.
