The dynamic for founders is completely different from employees in terms of work ethic, a job is a job, a company you own a large number of shares is a lifestyle choice of dedication. Nothing about the quotes seems to reflect a lack of ego, I would argue they all had a bit of ego in their earlier years. Each of the quoted were set on making a profound difference in world with their ventures. That in itself likely requires that you maintain the idea that your efforts and ideas have significant importance in the world and transitively you as a person have profound importance aka ego.
