He wasn't the only on, but was one of those guys who created this device that's giving this child a voice in the first place. You don't have to give huge chunks of money to charitable causes to be a philanthropic, you can use that money to build a company that makes people's lives better. Not that donating money is bad, just that there are different kinds of philanthropy. Jobs could've retired when he was 24 - he had about 400 million dollars then. But he tried to create a better company and lost almost all of it, and only years later regained his old wealth (in 2000+ he got I think hundreds of million of AAPL shares, and some years later got 7B selling Pixar to Disney).
He spent years and years of his life (yeas he could've enjoyed in Hawaii) building this very device; so, it's really unfair to not credit him for what he always aspired: changing the world (a little) and making a (small) dent in the universe.
And just to be clear: I'm not against capitalism. As much as it looks bad and IS bad, without capitalists we would have less progress in the world. As much as I love communism and socialism, they don't work really well in the real world (due to human nature, that's un-alterable).
So, don't judge entrepreneurs too harshly for not giving away their money.
