and how do you reconcile any work in software development? If someone isn’t willing to work for free, should they just not work in the field at all? Do you think software culture would really be richer?

My income is tied to the labor time I exert in creating/supporting services. I don't sit back and collect royalties on the code itself. Software is one of the first fields where the fundamental worthlessness of content revealed itself, hence FOSS.

When you watch a musical performance, you are also paying for labor. Even when you buy a physical art object, all the costs involved decompose back to labor. When you have a digital copy of something, there is no labor input to its creation, so guess what the inherent value is.

Animators drew actual cels. Theater workers clocked in and screened the films. The guys at the DVD factory pressed the discs. We paid for all of this already. It's double-billing to charge for copypasting the mere likeness of something. Nobody's doing any work for that.

You keep it in your house and charge people to come look at it (SaaS).

Those people sometimes look at it and build a copy (competitor) and that's okay.

You don't have to publish your code, or allow other people to run it.
