I have always hated the term GNU/Linux for many reasons, but mainly because of GNU’s self-importance, specially considering it’s not important at all.
Pedro Côrte-Real in his post “How much GNU is there in GNU/Linux?” arrives to many surprising conclusions (to some people).
1. In a typical installation, GNU software is less than Linux
2. Most of the software running on the system is not GNU (GNU is only 8%)
3. Most of the GNU software has popular alternatives in use
So, why on earth should distributions call themselves GNU/Linux? If you put GNU there, then you have to put KDE too, and why not Mozilla too?
The reality is that the only component that is not replaceable is Linux, and that’s how everybody refers to these distributions in colloquial language anyway. So let’s just get rid of the unpronounceable and inaccurate part.
