Book or other resources that relate open source to politics? Or simply books on how open source impacts our society? (without necessarily going deep into technicals)

During these holidays, I spent some time with my father in law. He had never heard of the term "open source" (although already kind of knowing what Linux is). He seemed very interested, and he is a very well read, politically engaged socialist*, yet I had trouble going more into details about how open source changes our current paradigm- both in terms of development and in term of ethos (as in proprietorship, privacy, etc). But I'm sure a book can do a better job at it than me.

So, I've decided to read up more on this subject myself as well as giving him some resources to inform himself.

I'm having some trouble finding stuff. Any recommendations?

* We are not in the US. So this is referring to the european meaning of the word.
