And you're right, he does state something close to the central point of my essay. But if you keep reading, that's not the part he tries to refute.
Your last paragraph is actually the most thoughtful response I've read about this whole controversy. But I think you're wrong to say that startups glorify the individual. The startup founders I know are on average more idealistic than people working for big companies. They tend to be the ones who want to make the world a better place; though there are of course exceptions, the people working at big companies are the ones who tend to think of their job as something they do mainly for the money.
