It's quite profit-perverted: the overarching goal is to conflate in the mind of engineers the idea of "hackers" - a group that traditionally is interested in the inherent joy of hacking and is skeptical of business-types - with the goals of venture capitalists and the lives of founders. It's not very explicit, and obviously I nonetheless find value here, but if you've ever seen someone build a technically interesting project and thought "Hey, they should get some seed funding and work on this full-time," then the HN gambit has been successful.

Thinking out loud,'I would gladly pay to be on hackernews ecosystem'.

And so would many organisations who would like to use it to influence hacker opinion.
