It is true that the Debian main repo includes packages with Artistic License
1.
In fact I went to read the license and then I went to check each package that
I have installed on my computer (Debian 8) with the command grep -i
'^License:.*Artistic' /usr/share/doc/*/copyright
Every installed package on my lappy that contains the Artistic Licence 1 also
contains the GPL1 or GPL2 or Expat or BSD 3/4 or several of the
aforementioned. Every single one of these packages are double or triple
licensed, which, in my very humble opinion means that every single one of
these packages are fully free software (the user can choose under which
license he modifies and redistributes the code).
In few words: Debian is 100% libre software.
