Wow, I'm shocked by your anger. His disowning the petty concept of a legal apology written in his name seems totally reasonable, mostly because the recipient is the UFC, and not an individual who suffered any kind of legitimate harm.
OK, maybe I was a little harsh. But it doesn't matter who the aggrieved party is. He took an action, and now he's trying to weasel out of it by saying, in effect, "yeah, but I had my fingers crossed behind my back, so it doesn't count."
I am reacting to his utter inability to take responsibility for his actions.
