I'm not sure what you're arguing here. There are important features missing in AMD's linux implementation, the ROCm ecosystem remains unsupported (on consumer hardware) under linux, and it relies on the same linux-firmware blobs as NVIDIA and everything else.

AMD is trying to get HDMI 2.1 support through legal, but they've been trying for years and the answer is generally "no". HDMI Forum doesn't want you to release open implementations, it is incompatible by design. This is a microcosm of the problems around licensing in the audiovisual space, the reason NVIDIA can't go open is also because of these intractible licensing problems. They just lean towards "release the functionality, but closed" instead of choosing "don't release the functionality".
