He was resourceful enough to find a security flaw of the highest severity in the only product of a $300 billion dollar company. A hole that was somehow missed by said company's own security auditors, who collectively are probably paid many millions of dollars per year entirely to look for such holes. So that's something.

But you're right, he might have just got lucky. The one fish in a school of 100,000 who finds the hole in the net probably isn't smarter than all the other fish. But that just strengthens the argument that companies should reward very generously for these exploits, because increasing the number of white-hats looking for them is a good way to ensure that they get found by one.
