GNU-Darwin

GNU-Darwin is a project to package applications for the Mac OS X and Darwin operating systems. They also distribute versions of the Darwin operating system (produced by Apple) and the OpenDarwin operating system which is based on Darwin, although the versions they distribute tend to lag behind the current releases. The project states that its goals are to "focus on projects that leverage our unique combination of Darwin and GNU, and help users to enjoy the benefits of software freedom."

GNU-Darwin is also a platform for digital activism. The project attempts to bring certain issues to the attention of software users, by highlighting them on their website, and on occasion "blacking out" their website in protest. They have highlighted such issues as the 2003 invasion of Iraq, Adobe's use of the Digital Millennium Copyright Act and the arrest of Dmitry Sklyarov.
