This has nothing to do with copyright.  This is a question of patent
infringement.  Please do not conflate these two areas of law.

You should stop filing multiple release critical bug reports for a legal
issue on which there is no conclusion.  Take this to debian-legal *first*,
and if there is agreement that these packages cannot be distributed by
Debian, *then* file bugs.

It is Debian's de facto policy that software patents are only an obstacle to
inclusion in main if there is both a history of enforcement and a reasonable
belief that the patents are not invalidated by prior art.  Please
demonstrate that this is the case for patents covering use of these codecs.
Note that the existence of voluntary licensees is evidence of neither
enforcement nor validity.

A conclusion for which you have provided no support whatsoever.
