summary of software licenses in non-free



so, what exactly is in non-free?

some people expressed doubt about the claims i made regarding the actual
contents of non-free.  i said that very few packages were proprietary, that
almost all were 'almost-free' (aka 'semi-free').

since no-one else has bothered to answer this question, i did it myself.  a
classification of every non-free package that was in my debian mirror.  a total
of 273 packages, but only 259 packages had a 'copyright' file (odd, i thought
there were more...about 350 or so.  we must have got rid of a lot of non-free
packages).

the facts conclusively support my claims.  out of all the packages in non-free,
only 9 are binary-only/proprietary.  the rest are almost-free (actually, there
are a handful of mis-classified packages which seem to qualify as DFSG-free)

btw, note that 273 non-free packages is miniscule compared to the ~13,000
packages in main.  only 2% of the total package pool.  it's amazing what a huge
fuss is being made over such a tiny number of packages.

if you want to check the licenses yourself, email me and i can send you a 300KB
file containing just the copyright files.  it's too big to attach to a mailing
list.

otherwise, make your own with this script (this will thrash the disks and take
ages to run):

--- extract.sh ---
#! /bin/bash

mkdir -p /tmp/debian/non-free
cd /tmp/debian/non-free
mkdir -p packages

for F in $( find /debian/pool/non-free/ -name "*.deb") ; do
  B=$(basename $F | sed -e 's/_.*//')
  echo "$B"
  mkdir packages/$B
  dpkg-deb -x $F packages/$B
done

mkdir -p LICENSES

for C in $(find packages/ -name 'copyright'); do
  B=$(echo $C | sed -e 's/packages\///' -e 's/\/.*//') 
  echo "$B"
  /bin/cp -a $C LICENSES/$B.copyright
done
--- extract.sh ---


i've made comments for each package, summarising how it deviates from the DFSG.
as i claimed in a previous message, the majority are because of no
sale/profit/commercial-distribution clauses.  the second most common are "no
distribution of modified versions" clauses.

i DID NOT exhaustively analyse each license.  i looked quickly at each one to
try to find out why it had been classified as non-free.  in some cases, that
means i may not have noted down all the reasons why a particular package is
non-free.

there may or may not be mistakes in the lists.  while there are no errors that
i know of, i'm tired and it is possible that i may have made a few mistakes.
feel free to correct them.




i have separated the non-free packages into four main groups: 

1. "BINARY ONLY" -- binary only, proprietary stuff.  9 packages total (or 6 depending
on whether you count groups of packages individually or not).

2. "X3270" -- by my reading of the x3270 license, there's no reason why it
can't go in main.  the maintainer is being, IMO, overly cautious.  7 packages total.

3. "POSSIBLE MISTAKES" -- other stuff that may belong in main or contrib.  9
packages total (or 7 depending on how you count them).

4. "ALMOST FREE" -- everything else.  234 packages.

i probably should have separated out the "no sale/profit/commercial use" ONLY
packages into a separate group.....but i've been working on this for hours and
i want it over and done with.  i'll leave that as an exercise for the reader.



anyway, here are the lists.



BINARY ONLY
-----------
eagle           binary only shareware.  free for non-profit use only - "If you
                earn money by using the Freeware version of EAGLE Light,
                you have to register it."

nvidia-glx      binary-only.  no modification, no reverse engineering.
nvidia-glx-dev  binary-only.  no modification, no reverse engineering.
nvidia-kernel-source    binary-only.  no modification, no reverse engineering.

rar             shareware.  40 days free use.  binary-only.  

unicorn         GPL, but with two binary-only object modules.
unicorn-source  GPL, but with two binary-only object modules.

upx-nrv         contains some binary-only, no source available code.

xtrkcad         binary-only. no separation of files. may not distribute
                xtrkcad.key file.


X3270
-----
x3270           seems to be free.  IMO, maintainer is overly cautious about
                license.
3270-common     same as x3270.
c3270           same as x3270.
pr3287          same as x3270.
s3270           same as x3270.
tcl3270         same as x3270.
x3270-htmldoc   same as x3270.


POSSIBLE MISTAKES
-----------------
edict           seems like it may be free. long & complicated license. strange
                requirement to make every effort to only distribute
                latest version. explicitly mentions personal use but
                does not prohibit non-personal use, in fact doesn't
                prohibit much at all. IMO, maintainer may be overly
                cautious about license...although i've only spent a few
                minutes looking at it.

edict-fpw       part GPL, part same as edict.

mmix-src        part GPL. part Donald Knuth license - modified files must be
                renamed and clearly identified. why is this in non-free?

mocka           BSD-style license with noxious advertising clause. why is this
                in non-free?

molphy          very simple license says it is "free software". fails to have
                an explicit clause allowing modification. clarification
                would be good, but IMO there is no compelling reason why
                this can't go in main.

mwavem          says license is GPL. why is this in non-free? does it contain
                binary-only driver or something??

sgb             modified files must be renamed and clearly identified.  why is this in
                non-free?

sl-modem-daemon looks like BSD-style license with noxious advertising clause.
                why is this in non-free?
sl-modem-source looks like BSD-style license with noxious advertising clause.
                why is this in non-free?
