I agree with you.
But why emphasize "economies" in this way? Do we talk about books like this?
Practical benefits have to flow from the ethical ones or else we're in danger of playing a game where economy is on top of freedom. See China: in the 1990s there was thought that democracy would follow capitalism. But no. You can have capitalism with no Freedom.
This book https://cloudempires.org/ is pretty good about this issue (though doesn't discuss FOSS directly)
