Here is an example question:

[Libreoffice 5.1.6.2 “The dictionary is already full.”](https://askubuntu.com/questions/940442/libreoffice-5-1-6-2-the-dictionary-is-already-full)

It is about LibreOffice, which is a package that is included in the Ubuntu ISO by default, but not made or maintained by Canonical or a second-party.

Why aren't these questions considered off-topic? They aren't about Ubuntu or a package that is included in Ubuntu **and** made or/and maintained by Canonical or a second-party that Canonical hired to maintain it.

**EDIT** What I really meant by what I said is programs that are not related to the system, such as LibreOffice, Blender, Inkscape, etc...
Stuff like Unity, GNOME, KDE, grub, lightdm, etc... should be on-topic.

I have no idea why I did not mention that in the original question.
