Where did I imply that he has told more than one?
It is a direct quote from the ask Adkins event.
If you are saying that this is not a lie as it could have been the board that took control and sold him, then in any case he's not damned if he does, and he's also not damned if doesn't. If the decision wasn't up to him there was no need to say "I", instead of "we".
He chose "I" because then if we didn't sell Murphy, he can appear as if it was he that didn't sell him and it was he that had ownership over the deal. But as we did sell him, the fact that he used "I" can allow him to appear as though he was completely detached from all responsibility.
He wins either way. Which is what he intended.
