I think you misunderstand the situation. The change implemented in the production kernel version, breaks drivers for all Nvidia cards. Why in the world would Nvidia want to do that? I could maybe understand Nvidia breaking compatibility for older Nvidia cards, to sell the latest ones, but there is simply no way Nvidia would want what is going on here; because even their latest cards won't work.

Also I think the kernel developers who push these changes that are designed to sabotage Nvidia and their customers need to consider that Linux may be used in e.g. critical medical equipment. If they want to humiliate Nvidia, they can make a CUDA competitor that is mature and widely supported, but instead, vandalizing other peoples' stuff seems to be easier for them to do.

Again, the breakage on display here is not a bug or mistake, it's a "feature", coded by someone to disrupt functionality on others' systems.
