There is no suggestion of compulsion in my comment. I’m asking that people stop hurting their fellow authors by participating in a race to the bottom, simply because they’re flattered that a for-profit corporation is willing to take their product for essentially no compensation. This has nothing to do with contributing to open-source software, working for nonprofits for a social good, etc. I do all those things. But if a business or a startup with dollar signs in their eyes wants to consult with me, or publish my work, they’re going to pay. And it’s unethical to give away your work under these circumstances.
Although I have sympathy for libertarian points of view, I think that minimum wage laws are important. Without them, you have a race to the bottom for wages for unskilled labor, resulting in widespread suffering. We don’t have minimum wage laws for writers or freelance programmers, so we have to depend on our personal ethics. Please stop giving away your product.
