This is branding and marketing issue. Anyone can implement the spec, it doesn't need to be a cleanroom implementation. It's almost certain that you could license the patents from the patent holders because HDMI doesn't develop it's own patentable stuff, they just get it from Sony, Panasonic, etc.
THIS IS A MARKETING / BRANDING ISSUE.
Saying they don't want an open source implementation is just a smokescreen. 99% of the implementation is in hardware anyway.
I need to post this everywhere:
THIS ISN'T AN IP/PATENT ISSUE!
