I like this description why people should mention GNU. With "open source software" or "Linux" or "Ubuntu" there are no moral implications, nothing to stand for except that it should do the job. But GNU is different. The idea is to emphasize sharing and freedom and community. In a world that is driven almost only by profit margins we do well to have some ideals. GNU has enabled Linux and Ubuntu to come to life. Without GNU there wouldn't be any Linux as we know it today. Also Torvalds had adopted the GNU GPL (what MS called the "cancer") for the kernel. Who knows where we would be if that wouldn't have been the case.
