King InuYasha writes "Nexuiz founder Lee Vermuelen, along with several other core developers, have licensed the Nexuiz name, Nexuiz.com domain, and DarkPlaces engine to Illfonic in a deal to get Nexuiz on consoles. However, the kink is that the engine has been licensed for non-GPL usage. That is, Illfonic has no intention of contributing their code back to the main GPL Nexuiz project. As a result, Nexuiz has been forked into a new project called Xonotic. While the main Nexuiz site doesn't mention that Illfonic has no intention of contributing back, the Xonotic project FAQ explains what's going on. Additionally, the Xonotic project states that Illfonic 'may be in violation of the GPL as most contributors to the Nexuiz codebase have not relicensed their work for inclusion in a closed-source project.'"
