Description

In Parabola's PKGBUILD of texlive-core, the following non-free components are removed:

   # remove nonfree packages
   # MeX licensed packages
   rm -v {cc-pl,cs,ec,mex,pl}.tar.xz
   # public domain, will be relicensed
   rm -v context-{account,algorithmic,letter,ruby}.tar.xz
   # no specific free license
   rm -v euro-ce.tar.xz

The following lines seem to be a direct consequence of this (see Bug #415: [texlive-most] Errors during installation).

  # remove nonfree packages references from updmap.cfg
   sed -i '/ccpl.map/d'       texmf-dist/web2c/updmap.cfg
   sed -i '/cs-charter.map/d' texmf-dist/web2c/updmap.cfg
   sed -i '/csfonts.map/d'    texmf-dist/web2c/updmap.cfg
   sed -i '/plother.map/d'    texmf-dist/web2c/updmap.cfg
   sed -i '/pltext.map/d'     texmf-dist/web2c/updmap.cfg

   # remove nonfree packages references from texlive-core.maps
   sed -i '/ccpl.map/d'       $srcdir/$pkgname.maps
   sed -i '/cs-charter.map/d' $srcdir/$pkgname.maps
   sed -i '/csfonts.map/d'    $srcdir/$pkgname.maps
   sed -i '/plother.map/d'    $srcdir/$pkgname.maps
   sed -i '/pltext.map/d'     $srcdir/$pkgname.maps

   # remove nonfree packages references from fmtutil.cnf
   sed -i '/cslatex/d'     texmf-dist/web2c/fmtutil.cnf
   sed -i '/csplain/d'     texmf-dist/web2c/fmtutil.cnf
   sed -i '/from mex/d'    texmf-dist/web2c/fmtutil.cnf
   sed -i '/mexconf.tex/d' texmf-dist/web2c/fmtutil.cnf

   # remove nonfree packages references from package list
   sed -ri '/^(cc-pl|cs|ec|mex|pl|context-(account|algorithmic|fixme|games|letter|ruby)|euro-ce) /d' CONTENTS

I looked at the Licenses and found the following:
The following packages have a free license and I propose therefore to not remove them.
  • context-account: Published in the public domain [1], and thus free [2]
  • context-algorithmic: Licensed under the GPL v3 or later [3]
  • context-letter: Licensed under the GPL [4]
  • context-ruby: Published in the public domain [5] and thus free [2]
  • euro-ce is licensed under the Modified BSD License [6] which is free [7]
For the following packages, I am not sure:
  • cs: I could not find the package in ctan. Is there another name for this?
  • ec: There were discussions in " Freedom issue #969: [texlive-core] ec fonts needs repackaging instead of removing" and a upstream report in [8]
  • mex: "The MeX package belongs to the public domain. The MeX package
    may only be distributed in unchanged and complete form ..." (in
    mexinfo.eng [9]). So is this free or not?

This package is no more contained in texlive-core. Due to `rm -rf` there was no error message.

ec

ec seems to be free software, but it is based on PL
  1. it refers to copyrite.txt (attached), which asks that any modified versions should be renamed to something different other than ec. (the name of the file is incorrect from the source) #969
  2. it says that some files may be exempt from that copyright if expressly mentioned
  3. no other files have such an exception (all have almost the same legend). I used this code to make the task easier (remove repeated lines to find those which had special notes):
    head -n 19 *.mf | grep -v '\(%[[:space:]]*$\|% (c) Copyright 1995, 1996, 1997 J"org Knappen\|% (c) Copyright 1996, 1997 J"org Knappen\|% This file is part of ecfonts version 1.0\|% Parameters for\|% European Computer Modern LaTeX Typewriter\|% (c) Copyright 1990, 1992 Norbert Schwarz\|% Please read the files 00readme.txt, 00inst.txt, 00error.txt, and\|% copyrite.txt for further information\|% You find some documentation in ecdoc.tex (needs LaTeX2e)\|% Content:\|%    Parameter for\|%    European Computer Modern Bold Extended Text Italic\)'
    

The only remarkable notes were for these files, but they do not seem affected by license issues in any way:

I already sent an e-mail to Gerd Neugebauer (gerd [lives at] informatik dot uni-koblenz dot de) to see if he wants to add a free license to PL.

cs

cs should be csfonts (download the sources from Arch and check one of the .mf files) and is free software (GPL)

mex

Free software should be readable, sharable and modifiable, so I don't think that "unchanged and complete form" qualifies (at best, it would be open source).
