The idea of free software is extremely socialist/communist. People working together to create something that anyone can use for free, with profit being a non-existent or at least minor motivator.
The expansion of the Internet has witnessed a resurgence of the gift economy, especially in the technology sector. Engineers, scientists, and software developers create open-source software projects. The Linux kernel and the GNU operating system are prototypical examples of the gift economy's prominence in the technology sector and its active role in using permissive free software and copyleft licenses, which allow free reuse of software and knowledge.
Essentially the line of thought is that open source software is an example of mutual aid and the gift economy.
Cory Doctorow has a book, "Walkaway" that is basically exploring the politics of FOSS on a societal scale. It's pretty nerdy obv but I enjoyed it and it doesn't overly glamourize any political system the way you'd typically see in political fiction.
I made a commentary about it here https://lemmy.ml/post/511377 in the FLOSS vs Closed Source Philosophy section:
The soul and spirit of FLOSS is socialist/communist, in a similar way to piracy. The purpose of it is to serve the greater good. In comparison, the soul and spirit of closed source software, outside rare cases of benevolence, is highly corporate and fascistic, similar to a leech, which in many cases these days may suck money out of your wallets for subscriptions. It may also serve as a leech to suck your data for telemetry and spying purposes.
Idk, technically voluntary association is a key tenet of volunteerism/anarcho-capitalism, so if we're just using volunteering as the basis we might as well say it's volunteerism. I think anarcho-communism and anarcho-capitalism are a bit more nuanced than "sharing."
What's the real difference between an "anarchist communist" and a "communist"? The first one can have "personal property" while the second cant? So... an anarchist communist can own a car but not a house? According to the internet "personal property" is everything that can be moved (not real estate) and isn't considered for production of something...
And the FOSS system seems to be collapsing right now for the same reason that anarcho-communism only works short-term until someone sees commercial value in it and abuses the system to the limit.
Big corporations initially providing exceptional services based on FOSS and after a while use their market share to excert undue control about the system (see e.g. RedHat, Ubuntu, Chrome, Android, ...)
Big corporations taking FLOSS, rebranding it and hiding it below their frontend, so that nobody can interact with or directly use the FLOSS part (e.g. iOS, any car manufacturer, ...)
Big and small companies just using GPL (or similar) software and not sharing their modifications when asked (e.g. basically any embedded systems, many Android manufacturers, RedHat, ...)
Big corporations using infrastructure FOSS without giving anything back (e.g. OpenSSL, which before Heartbleed was developed and maintained by a single guy with barely enough funding to stay alive, while it was used by millions of projects with a combined user base of billions of users)
The old embrace-extend-extinguish playbook is everywhere.
And so it's no surprise that many well-known FOSS developers are advocating for some kind of post-FOSS system that forces commercial users to pay for their usage of the software.
Considering how borderline impossible it is for some software developer to successfully sue a company to comply with GPL, I can't really see such a post-FOSS system work well.
