There is a war going on with many big faces in Crypto and Craig Wright has started off another big tirade against the Crypto- Bitcoin world in general, so maybe McAfee is trying to end this by wanting to Reveal Satoshi Nakamoto's identity in order to put all this to rest. I can't really put my finger on any other intentions and I doubt that he is doing it purely for sensationalism and fame, as that doesn't make much sense. Then again what does in Crypto?
I would prefer it for Satoshi Nakamoto to remain hidden, purely for his own safety at this point in time.
