The point is, Cory Doctorow is in a small, small minority. The minority isn't small because people don't know what he's saying -- it's small because they don't care. He's protesting the very philosophy that gives Apple products the quality that people who buy Apple products desire. And honestly, making the openness of Apple products your raison d'etre is a bit like getting furious about the mechanical details of your favorite brand of dishwasher. The answer is always the same: don't like it? Don't buy it.
Cory is more than welcome to continue to post these sorts of rants on his blog, of course, but let's not turn them into more than what they are: one guy, forcefully advocating an opinion about something that really doesn't matter that much to most people, and that he can't really change.
