Oh Well

Selig will not reverse umpire’s blown call

I still think it's dumb, pig-headed, stubborn, and unnecessary not to overturn the call. From a general life philosophy perspective, if you have the power and means to correct a mistake, shouldn't you?

That said, changing the call wouldn't give the players or the fans back that moment to celebrate. It might have healed some wounds, but the damage was done. After all, you can't have a perfect game with an error, even if that error was by an umpire. One way or another the game was always going to be the "Imperfect Perfect Game".
