The majority of real hackers here on HN have almost certainly contributed to an open source project and many have released their own work as open source.

The startup ecosystem exists, in large part, because a huge number of hackers created and freely gave away things like GCC, *BSD, Linux, PostgreSQL, MySQL, Redis, Apache, Nginx, Ruby, Python, etc. Without free, open source, software large amounts of funding would be necessary just to acquire the tools needed to build software systems.

People admire Louis CK's position because it strikes a good balance between the need to make money and the desire to share.
