Intel managed to do it for their audio firmware, so why not GPU firmware too?

Of course, for most of the supported hardware, the firmware is open source but not libre because of signatures. There is some supported hardware where you can sign using a published "community" private key though. Eventually they may make a Secure Boot style setup with user-enrollable keys though.

Complexity, mainly. Apparently, the firmware for something like the recent NVidia/AMD GPUs has millions and millions of lines of code. Tightly coupled to specific hardware.

They are rumored to be full computer systems in their own right, though probably not Linux systems. Heck, the NVIDIA GSP is a full RISC-V computer. So the firmware is an operating system payload for that computer.

The same goes for probably most firmware I guess

SOF itself can be based on two different embedded OSes; XTOS or Zephyr.

This reminds me that hardware vendors have been moving Linux off into a corner for years:

To me complexity sounds more like an argument for open sourcing it since complexity naturally prevents a competitor from copying your solutions in a reasonable amount of time so there is really no trade secret angle to be used to justify closed source code bases.

Probably the real reason is that they don't own the IP and cannot reasonably get the rights for it to be open even if they wanted to.
