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. (but they share some parts: https://opensource.apple.com/ . But the process of development is not shared, releases are cleaned)
