See my analogy below in this thread about the public park...

What is incomprehensible is developers confusing the value created by the site, with the means of production of said value.

While contributing to the site might provide you with some personal feelings of value, maybe even a rush of altruistic euphoria... :-) An illusory sense of digital sainthood...Your unpaid work directly enhances the value of a platform that profits from selling the collective output, including yours.

This means you’re effectively donating your expertise to a for-profit entity, with no equity or share in its success
