I'm not entirely sure what point you're trying to make here. I didn't suggest the entire stack has to be open source, nor am I looking for a reason to use NVIDI

I'm not entirely sure what point you're trying to make here. I didn't suggest the entire stack has to be open source, nor am I looking for a reason to use NVIDIA on Linux. I just think it would be great if NVIDIA open sourced whatever portions of their graphics driver to make the Mesa implementation competitive.
