I remember reading such forum posts from John Bridgman several years ago. The argument assumes that no one can reverse engineer that firmware. This is false: Nouveau developers replaced much firmware with other custom instruction sets, and found security issues in NVIDIA's firmware. At least some of AMD firmwares are easy to reverse engineer, just no volunteer has both skills and time to do it: this wouldn't be a problem for AMD's competitors who could just hire someone. There is a similar excuse regarding patents debunked at http://libv.livejournal.com/2014/07/16/ (see the paragraph on AMD drivers too).
