> Open Source volunteerism is the result of the early hacking culture

I don't agree with that take. There was not, to my knowledge, a "volunteerism" component of either early open source or early hacking culture (though my roots only go back to about the mid-80s). The "volunteer" part came later, as there was an explicit effort to emphasize open source as free as in free labor. What I used to see was openness in the sense of knowing what the code did and being able to make changes if you want. It was more of scratching your own itch and letting others play with the code if they wanted.
