I dont know if you read everything or simply saw linux, then posted this. I use Linux as general term for a Linux-based System, since GNU-System is normally nothing more than GNU-Tools running on Linux.
A kernel is not very useful without the rest of the OS. The FreeBSD developers would probably be offended if you called Debian GNU/kFreeBSD just "FreeBSD".
The non-technical People on this world normally talks about Linux, when it comes to Systems running on Linux.
Sure, which is why we're here to explain the difference. :-)
And not about GNU-Systems. IF we want to explain such Systems to non-technical People, we should use Words they already know.
When people found out that the world was round, should people have continued telling kids that the world was flat?
The GNU Tools are invisible to most users that only use a desktop Environment like Gnome or KDE).
GNOME is a part of the GNU project. Many GNU/Linux distros use GRUB, a GNU project. Maybe there will be once or twice when a non-technical user will open a terminal window, with a GNU Bash backend. And don't forget The GIMP. ;-) Andrew.
