You are confusing $500K worth of "work" with $500K worth of billing. A common problem in our industry.

$50,000 seems pretty exorbitant for a "simple" app that does nothing more than embed YouTube videos.
$50,000 for the literally 5 minutes of work involved in changing the channel ID and app name is downright comical.
There's no way to spin this as $500,000 worth of work. I don't care what his billing rates are. (And I suspect his billing rates aren't very high to begin with — he doesn't strike me as the sharpest tool in the shed.)
You are making a common mistake on pricing something based on the amount of work it requires, not on the amount of value it provides. I can't imagine that a rebranded youtube viewer provides 50K worth of value to anyone, but it wouldn't be nearly the most outlandish work/value ratio I've seen.
