I (who am not the OP) would feel better if he gave the money to himself, then he used the money for charity.
In the blog post, Louis states that money is "the money" not "his money," and that "the money" is going towards charity.
What he should have said was "I am receiving 500k of "the money" to which I am giving 280k of it to charity"
It's a semantic argument, but for some reason it means something to me.
