Relevant Section under Gift economies:

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.
