IconThanks to SGI, a potential disaster for Free software purists has been averted. Back in January 2008, it was discovered by the OpenBSD guys that some of the contributions to X.org and the Mesa 3D Graphics Library made by SGI were covered under permissive open source licenses that didn't fall within FSF's definition of Free software. The FSF Compliance Lab worked with SGI to resolve the issue, and they succeeded.
