The movie studios. As the person above said, the HDMI consortium (owned by movie studios) is focused on protecting their members IP rights from pirates. HDMI has built in DRM, that could be removed from an open source driver.

    Well, one of the master keys leaked about 15 years back. A researcher posted a paper back in 2003 or so that outlined a method of finding a master key that was likely used by the people who made the release. It was a fun time to be on the internet, the people came together and said, yeah fuck those corpos and everyone reposted the key to every form of social media possible. I knew someone with the key tattooed on their arm (as part of their piracy themed artwork, I used to have pictures)

    Now, that particular master key was patched out with a compatibility breaking upgrade, specifically 2.1 of the standard, which was proven to be broken in 2012, but there was less coming together to share it the second time, or the third for 2.2 of the standard.

    But yes, if you wanted to code your own, you easily could. Just don't share it or the sue happy corpos will come knocking.

    Maybe it is the movie studios, but there don't appear to be any of them on the list of HDMI Forum members, or on its board of directors. So my first guess was some combination of Microsoft, Nvidia, Sony, and Apple. Whoever it is though, the question is how they went about convincing the HDMI Forum as a whole to take such a self-destructive approach.

    The HDMI founders were Hitachi, Matsushita (now Panasonic), Maxell, Philips, Silicon Image (now Lattice Semiconductor), Sony, Thomson (now Vantiva), and Toshiba.[3] Intel contributed the HDCP copy protection system.[4] The new format won the support of motion picture studios Fox, Universal, Warner Bros. and Disney, along with content distributors DirecTV, EchoStar (Dish Network) and CableLabs.[2]

    While Sony is a technology company, they're also a very sue happy IP holder through Sony pictures and Playstation.

    Sony continues to be a major player on the HDMI forum.
