Hmm, before being able to download, I had to agree to a EULA that had this in it: Further, Brother shall have no liability to disclose and/or distribute the source cord[sic] of the Software to User under any circumstances. In no case shall the above license by Brother to modify, alter, translate or otherwise prepare derivative works of the Software be construed as Brother's implied agreement or undertakings to disclose and/or distribute the source cord[sic] of the Software. That flies straight in the face of this from the GPL-v3 preamble: [...] General Public Licenses are designed to make sure that you have the freedom to distribute copies of free software (and charge for them if you wish), that you **receive source code or can get it if you want it**, that you can change the software or use pieces of it in new free programs, and that you know you can do these things. # Emphasis is mine. I've let Brother know via the Content Feedback shown for the download and suggested they fix the discrepancy, preferably by distributing the source code. # Not holding my breath on anything getting actually done, but ... who # knows, they might take notice. BTW, the EULA does grant: [...] User a non-exclusive license: to reproduce and/or distribute (via Internet or in any other manner) the Software. Further, Brother grants User a non-exclusive license to modify, alter, translate or otherwise prepare derivative works of the Software and to reproduce and distribute (via Internet or in any other manner) such modification, alteration, translation or other derivative works for any purpose. That's in line with the GPL but utterly useless without access to the source code. I did a quick check on the contents (btw, everything in usr/lib64 is a copy of what's in usr/local/lib64, bloating the package by ~100%), but all the libraries only seem to link to LGPL'd libraries (or GPL-v3 with the a GCC Runtime Library Exception). This makes me believe that Brother can change the license to whatever it pleases (within the LGPL limitations on debugging for reverse engineering purposes), assuming they own all the other code that went into those libraries. The libsane-brother_pdsseries backend uses some code from sanei/, but all of that is GPL with a special exception. The exception is that, if you link a SANE library with other files to produce an executable, this does not by itself cause the resulting executable to be covered by the GNU General Public License. Your use of that executable is in no way restricted on account of linking the SANE library code into it. This exception does not, however, invalidate any other reasons why the executable file might be covered by the GNU General Public License. which is pretty much what the LGPL does too. # The SANE licensing approach predates the LGPL, IIRC. In short, I'd say that Brother made a very bad-tasting mistake labeling their Debian packages as GPL. Whether on purpose or not, I don't know, but next time make sure to read the EULA before you click agree ;-( Hope this clarifies, -- Olaf Meeuwissen, LPIC-2 FSF Associate Member since 2004-01-27 GnuPG key: F84A2DD9/B3C0 2F47 EA19 64F4 9F13 F43E B8A4 A88A F84A 2DD9 Support Free Software https://my.fsf.org/donate Join the Free Software Foundation https://my.fsf.org/join -- sane-devel mailing list: sane-devel@lists.alioth.debian.org http://lists.alioth.debian.org/cgi-bin/mailman/listinfo/sane-devel Unsubscribe: Send mail with subject "unsubscribe your_password" to sane-devel-requ...@lists.alioth.debian.org
