I am looking for works about free software or based on this philosophy, there are books like “Free software for a free society” and documentaries like “Linux code”, but I would like to know what other works there are related to free software and this philosophy, there are things like snow crash, which talks about the decentralization of the internet from a fictional and futuristic story, these types of works are also valid.
If “Snow Crash” counts, you probably want to look into the novels “Daemon” and especially its sequel “Freedom” by Daniel Suarez. Probably also the novel “Walkaway” by Corey Doctorow.
“The Internet’s Own Boy” is a documentary about Aaron Swartz that I suspect would also scratch your itch. (Available on Archive.org)
Also Doctorow’s novella “Unauthorized Bread”.
Is “The Public Domain” public domain? Or proprietay?
