NVDAs foothold here is not about gaming, but machine learning. Few people play on Linux anyway, but machine learning is basically not happening without Nvidia. Not that this is favorable, but it is true. And yes, I am taking it, I simply do not care that much.
And I am guessing ML workloads use up a single computer to do just that (and nothing else), meaning that NVidia could start their own fork of Linux, and people need to just eat it (or switch to AMD, Intel, etc.!)
