      It is closed in the sense that all the ISO specs are closed - you have to pay a decent sum of money to see the specs, and you’re not allowed to just copy them and show them to people that haven’t bought access.

      They are not closed like HDMI though - if you implement them, copy constants from the specs into the Linux kernel for example, that’s fine. Having actually open standards like Wayland would be a lot better though ofc…
