Personally I don't give a shit how angry or insane he may appear to be. He did a good job finding the exploit and did a good thing being public about it.
So he deserves not only to be thanked for finding the bug, but he should be thanked for being honest about it. There is money to be made in 0-day exploits and he could of profited from it financially before going public, if he ever decided to go public.
So that is something that I can appreciate quite a bit.
