The “free rider problem” has been used to justify licenses that protect the interests of software authors since before we called it “open source”, long before Amazon was made a scapegoat.
“The free rider problem is when someone is allowed to package free software in non-free or less-free bundles, and that's precisely the area of the GPL that I thought I needed to do something about in making the Aladdin license”—Peter Deutsch, October 1998 [1]
The point I am trying to make is that legal tools like the Aladdin Free Public License and SSPL do not protect FOSS, or advance the social movements that have produced a bountiful commons of digital public goods. Those that craft those tools and apply them to their works have every right to do so, but they do so because they choose to do so, not because a company like Amazon “forced them” to.
