I'm not sure I understand what is illegal about Negativo distributing an
fdk-aac package and an ffmpeg package that links to the fdk-aac libraries
dynamically. If you statically linked to a non-distributable library then
you'd have problems. It's true that there could be some patent issues in
certain countries and fdk-aac is not GPL, but this is also why you need to pass
--non-free to configure to enable it. I think this is why it's discouraged.
This is more an aside and regardless this is definitely in the nonfree section.
This is the relevant clarification for anyone willing to investigate it:
http://www.gnu.org/licenses/gpl-faq.en.html#GPLAndPlugins
Also, just dynamic linking (as opposed to plugins) is no different to
static linking within the GPL license terms. The situation is
different for LGPL, but a project such as ffmpeg, which is principally
a libraries effort, have probably given some thought to the difference
between the two.
