List of proprietary source-available software

This is a list of proprietary source-available software, which has available source code, but is not classified as free software or open-source software. In some cases, this type of software is originally sold and released without the source code, and the source code becomes available later. Sometimes, the source code is released under a liberal software license at its end of life. This type of software can also have its source code leaked or reverse engineered.

While such software often later becomes open source software or public domain, other constructs and software licenses exist, for instance shared source or creative commons licenses.[1][2] If the source code is given out without specified license or public domain waiver it has legally to be considered as still proprietary due to the Berne Convention.

For a list of video game software with available source code, see List of commercial video games with available source code. For specifically formerly proprietary software which is now free software, see List of formerly proprietary software.

[...]that no further patches to the title would be forthcoming. The community was predictably upset. Instead of giving up on the game, users decided that if Activision wasn't going to fix the bugs, they would. They wanted to save the game by getting Activision to open the source so it could be kept alive beyond the point where Activision lost interest. With some help from members of the development team that were active on fan forums, they were eventually able to convince Activision to release Call to Power II's source code in October of 2003.
