I think he uses the word communism to show a contrast with our current form of capitalism. In the current system established corporations keep increasing their profits while keeping the workers' wages flat since 1970. Because of computers, outsourcing, there is a surplus of workers, who generate increasing profits for the corporations. Much of the profits go to a small board of directors, who in turn use them to undermine government that was expected to look out for the workers. Startups are a holy grail because they share profits with more workers, supposedly. I'm just summarizing his emotionally charged lecture here, I don't fully agree with his premise, but it's an interesting perspective.
