Yes, I am nobody of importance. So I can call it GNU + Linux all day long and ignore the reasons for why not.
GNU was the ascribed name given by the FSF to their as-of-yet unfinished project to create a "free Unix"; The core components of that described OS at the time were a kernel, a basic text editor, a command shell, and a C compiler. These came in the form of Ed, BASH, and GCC. However, the kernel, known as HURD, has not yet materialized. Or maybe it has. Just not in a functional form.
Even if we account for the many other things the GNU project contributes to most Linux distributions, (and there are a lot); the sum of all those parts is not made up of only the Linux Kernel and those GNU components; there are significant pieces shipped with almost any Linux distro that have nothing to do with the GNU project. Some of them aren't even licensed under the FSFs preferred licenses(the horror). The big one being X11, which isn't from GNU nor is it GPL; the Qt framework isn't GNU and isn't GPL and is included and used quite a lot within Linux. Many of the portions used in most linux distributions in fact use BSD-licensed products, such as the init daemon; Should we now call it GNU/Linux/BSD?
Even the FSF page on the subject pulls statistics and can only come up with the stat that GNU code contributes 15% of the total size of most distributions. Truly, this is nothing but absurd narcissism. 15% of the codebase is a minority. The entire purpose of free software is that the best parts to do a specific task are used, re-used, modified, pass around and compiled into various usable operating system distributions for various purposes; or not. It's software. It's out there if someone wants it- many other packages are included in a distribution like Mint or Fedora, and most of them are essential in delivering the User Experience. To Trivialize all of the other excellent software that goes into a complete Operating System like Fedora Core, Debian, or Ubuntu should be defined by what the GNU project claims is the largest single contributor is nothing but arrogance. The largest contributor is not GNU. It's the community.
