However, it is trivially easy to use the
    gNewSense apt system to install unfree software.

Any general-purpose system can run non-free software, but that's not
the issue.  The issue is whether a distribution refers people to the
non-free software or not.

Since so many messages have been based on disregarding that
distinction, I suggest that everyone reread the paragraph above.

Ubuntu does many things that suggest installing non-free software.  I
did not know about this example, but I know of others which are worse.
That is why I refuse to recommend Ubuntu.
