You are perhaps correct. Startups are new kind of business model where you might not have to be constrained by stiff competition. You can just create something awesome and be acquired by people who then turns it in to business and fends off the competition. But then again, this doesn't support pg's thesis in its totality that no one has to be mean. People who run actual businesses in very competitive space probably have fewer options as opposed to startup founder who just want to create something interesting and sell off as one-time event.
