Free BSD was the basis for Darwin https://en.wikipedia.org/wiki/Darwin_(operating_system), used for MacOS. Permissive license, so Apple doesn't need to share their modifications.

"The peer production license is an example of the Copyfair type of license, in which only other commoners, cooperatives and nonprofits can share and re-use the material, but not commercial entities intent on making profit through the commons without explicit reciprocity. This fork on the original text of the Creative Commons non-commercial variant makes the PPL an explicitly anti-capitalist version of the CC-NC."
