I think technical people believe in the free market too much without understanding all of the requirements. One of them is that everyone has perfect knowledge of all options. If someone doesn't know about you, they can't choose you. This is why marketing adds so much value - you become an option and your technical merits have a chance to shine. If you market something crappy, you'll only succeed if no one knows about the better alternative.
