Information asymmetry is always the biggest business.

I saw a free open-source tool called "Life K-Line," which the author made available to the community. As a result, someone directly moved it to a certain platform and packaged it as a paid course for sale. The users who paid? They just got a link pointing to the original free website.

This move indeed inspired many "entrepreneurs"—how to achieve information arbitrage with minimal cost. This is also common in Web3, where project teams reframe their narratives to raise funds again, and community tools are repackaged as knowledge products... Interestingly, everyone is well aware of this, but transactions still happen.

On the other hand, this also reflects how much the understanding of "what is truly valuable" varies within the ecosystem.
