From the article: ”Do you think Brian Chesky of Airbnb heard that strategy from a friend? Hell, do you even think that freeriding off of Craigslist was their reason for success?” Yes, freeriding off of Craigslist was the reason for their early success, without which their later success was not possible. Having a good model means absolutely nothing without some ability to market it, especially in the marketplace space…
It's a common conceit of Industrialists (or at the very least, American Industrialists) to claim that they hoisted themselves up by their bootstraps and that their success is entirely their own. And then they begrudge paying for the sorts of public works and infrastructure projects that kept them from a lot more adversity. Hell, some won't even mentor or help people the way that people looked after them when they were young and naive.
