His point is, if mixxx can support plugins for the patent-encumbered codecs, 
then it can MOVE to Fedora and RPM Fusion can ship a mixxx-freeworld plugin 
that works with the Fedora mixxx (the preferred way to package support for 
additional codecs in RPM Fusion) rather than a package that Conflicts (a 
solution that is only used as a last resort).
