Well, to be fair, the author only has one paragraph about Apple and the Internet, and you could get multiple readings from it :) When I read control and centralization, I don't just think of iTunes, but I do think of Apple's dogged insistence that everything you do is essentially tied to one machine. Your iPhone, and (as I think Tim Bray described it "monsterously") your iPad, need to be sync'd to a computer when they start up, for no compelling reason. My Android phone lets me type in my Google ID and off I go.
Honestly, I think Apple's attitude towards the Internet is not because they don't like it. I think they just don't know what to do with it, certainly aren't willing to partner with companies that do, and they're letting their market get chipped away little by little. I've felt like Apple have been resting on their laurels for years, software-wise. Jonathan Ive is producing great hardware, but year on year competitors are catching up or surpassing Mac OS X and iOS, and Apple doesn't seem to notice/care.
