That wasn't meant to be the implication. If I had my time again, I'd add the word "mostly" to the last sentence, but apart from that I'll just clarify. The point I was trying to make is that using open-source, in the way Apple has, allows the customisation to go beyond the mere gluing together of black boxes. The thing Apple has woken up to is that 95% of the black box is reusable commodity stuff and it's that customised 5% that makes it "sing" with your hardware. This level of integration just isn't possible without the source code. You can try writing everything yourself, but that blows time to market, and required development resources, out big time.
