Ubuntu GNU/Linux, drafts for correct formulations

 status Rejected

This is not a bug in Ubuntu.

It is bug in Ubuntu, definitely. You can find it in many packages and on the Ubuntu website as well.

For example I see it in "About Ubuntu" dialog:
"Ubuntu is an entirely open source operating system built around the Linux kernel."

It should be:
Ubuntu is an entirely free software and open source operating system distribution based on the GNU operating system and the Linux kernel.

I can confirm this bug.

ubuntu should use the right names and phrases

Where mentioning "open source" it would be nice to say "free and open source" but other than that, you say:

  wrong: Ubuntu - Linux for Human Beings!

Ubuntu is a Linux based OS for "Human Beings". This is correct, of course, it also may be written as GNU/Linux to be more precise, but it is not wrong simply because it omits that information.

  wrong: distribution based on Linux
  wrong: Ubuntu operating system built around the Linux kernel

It clearly is a distro based on the Linux kernel, that is not wrong. It is also based on a myriad of other utilities. You simply cannot credit everyone in the name, I've never seen a requirement in a license requiring name-based attribution.

  wrong: Ubuntu is an entirely open source operating system...

That possibly is wrong, or at least very least misleading. It would be nice to include "free" software in that attribution since it is at least possible/practical to credit the movement.

This is not a bug. The words we use to describe to Ubuntu were chosen quite deliberately.

The official name is 'Ubuntu' and 'Linux' only appears in the tagline. We give credit to both the FSF and Linus (and the team), but not necessarily in the name.
The tagline uses 'Linux' for practical purposes, as it is easy for the afore mentioned beings to identify. It is very unfortunate that they are not very aware of what the GNU is and what it stands for, but perhaps Ubuntu should help the cause elsewhere. Using 'GNU/Linux' instead of 'Linux' where 'Linux' serves the purpose better will probably not do the trick.
