The details are documented here: <https://metadata.ftp-master.debian.org/changelogs//non-free/f/faac/faac_1.30-1_copyright> Here's the relevant excerpt: --8<---------------cut here---------------start------------->8--- Files: libfaac/bitstream.* libfaac/channels.c libfaac/filtbank.c libfaac/tns.* Copyright: © 1996-1997 License: other This software module was originally developed in the course of development of the MPEG-2 NBC/MPEG-4 Audio standard ISO/IEC 13818-7, 14496-1,2 and 3. This software module is an implementation of a part of one or more MPEG-2 NBC/MPEG-4 Audio tools as specified by the MPEG-2 NBC/MPEG-4 Audio standard. ISO/IEC gives users of the MPEG-2 NBC/MPEG-4 Audio standards free license to this software module or modifications thereof for use in hardware or software products claiming conformance to the MPEG-2 NBC/ MPEG-4 Audio standards. Those intending to use this software module in hardware or software products are advised that this use may infringe existing patents. The original developer of this software module and his/her company, the subsequent editors and their companies, and ISO/IEC have no liability for use of this software module or modifications thereof in an implementation. Copyright is not released for non MPEG-2 NBC/MPEG-4 Audio conforming products. The original developer retains full right to use the code for his/her own purpose, assign or donate the code to a third party and to inhibit third party from using the code for non MPEG-2 NBC/MPEG-4 Audio conforming products. This copyright notice must be included in all copies or derivative works. --8<---------------cut here---------------end--------------->8--- I also confirmed by looking at the indicated source files in the result of "guix build -S faac". Not only do these copying permission notices fail to grant the freedoms required by the free software definition, but they explicitly say: "The original developer retains full right [...] to inhibit third party from using the code for non MPEG-2 NBC/MPEG-4 Audio conforming products." That clearly contradicts freedom 0. Based on the file names, I very much doubt that this library works at all without the nonfree source files. Therefore, we must remove the 'faac' package from Guix. Thanks, Mark -- Disinformation flourishes because many people care deeply about injustice but very few check the facts. Ask me about <https://stallmansupport.org>.
