No, it's not. That gets at the very essence of my original comment.
One of the assertions in the article is that a hacker culture is a necessary ingredient for a successful technology company. I see Apple as a counterexample to this argument. And it's a counterexample that shouldn't be ignored. Apple is driven by design (industrial design, product design, graphic design). They think about products, not technology. They often invent new technologies to enable their products, but that's very different from thinking primarily about technology (a mistake, I would argue, that Google is guilty of frequently).
Taking as an example a project like Google Wave, I would even go as far as to say that a strong hacker culture and an obnoxious elitist culture of hiring only the best programmers can be serious detriments to a technology company. YMMV, but, culture-wise, I'd much rather build (and work for) an Apple than a Google.
Edit in reply to your reply: I thought it was any company that needs to have good software. But even so, surely Apple doesn't pay significantly more than Google (a hacker-centric company) and surely they're in roughly the same domain (iOS/Android, iAd, etc.). I think the real problem is in your next sentence: Otherwise you can't attract good programmers to work in a suit-centric culture. That's a big false dichotomy. Sure, suit-centric technology companies will fail. And hacker-centric technology companies sometimes succeed. I think Apple shows that a culture that is neither suit-centirc nor hacker-centric is the best option of all. If many of your YC companies are trying to build great technology companies, they should take that to heart.
