I don't think anybody can come up with better intentional snubs at Nvidia than the Nvidia itself.
When it comes to their older graphics hardware, their drivers just refuse to work with newer kernels. GPU was capable to draw windows and play videos for a decade, but then, after a kernel update, it doesn't even show 1024x768 "garbage". Just black screen.
So effectively, buying Nvidia to use with Linux equals to buying hardware with expiration date.
