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:

libfaac/filtbank.c

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.

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
