What Jobs probably meant (not that I agree with it necessarily): Philanthropy is using money to enable others to innovate, in contrast to being an innovator.

I think the article, although biased, maintains the basic assumptions really well. They are: Steve Jobs is a genius, at tweaking not inventing. Whether the reader agrees to this or not, is a different case. But this sections highlights the difference quite notably.

To think of it, the article talks about the scale of Philanthropy of Gates in fields like Malaria eradication. This is a grande project, in it's entirety. There are no existing systems that work and Gates imagination of a possible solution cannot be ignored as is done by Jobs. This does make Jobs narrow minded in the way that he is considering only Technicalities and Design as imaginative and completely denying the imagination that might go into believing in a better (and in this case malaria free) future.

I agree that he meant something along those lines. Not being a philanthroper, I probably shouldn't comment, but I think says a lot about the man (essentially the point that the OP made, that he was a narrow genius)
