Re your 2: it's not really up to Monsanto to restore the deleted articles. It's not his call, and if it went through Afd once, to recreate the articles would be to see them get redeleted.
But why would he apologize? He sees himself as following the letter of the law, and points out that if this is an issue, change the law.
Honestly this sounds like 2 things -
A cry of help from Wikipedia stating they need concerted outside help/force to fix something they can see is broken/can be improved
A lawyer saying that its not his fault the rules are what they are.
A sincere apology would involve 1) apologizing/admitting wrong-doing and 2) undoing the damage. I could certainly settle for only the second.
