As long as the code running on the Linux side is open and the closed source firmware stays on their chip that's fine by me. At least then you have a fighting chance to change the open source side up to date to allow the card to keep working.

I know it's not pure freedom but I'm picking my battles these days and if I can keep something working by bridging the gap between an evolving kernel and static closed firmware then that's good enough for me.

I have an Intel NUC based iGPU and it works with Linux-Libre + MESA. OpenGL and Vulkan. Ok, just libre games/engines, but they with all the FX'.
