I think the guy sounds genuine enough. He has explained his position, on which he's actually right, there isn't anything specific in the rules about using programmes.
He's also said from now on he'll inform his opponent that he may use a programme. What more can you ask? He's been very open and upfront in my opinion. Give him a break!
