But if they make money with someone’s years of work writing a book, then please give that author some money as well.

Why? I’ve read many books on programming, and now I work as a programmer. The authors of those books don’t get a percentage of my income just because they spent years writing the book. I’ve also read (and written) plenty of open source code over the years, and learned from that code. That doesn’t mean I have to give money to all the people who contributed to those projects.

Just because you work on something and release it to the world, doesn’t mean you are entitled to make money off it.
