Nvidia has been slowly trying to open a little over the years; first GBM support in the proprietary driver then the open OOT module and finally GSP firmwares for the kernel; allowing an OSS kernel module to exist.
The OSS graphics community has obviously shown that it doesn’t want Nvidia’s open module (which is tied to the proprietary driver anyways) and would rather build out its own OSS drivers atop an adapted Nouveau/NOVA. Perhaps Nvidia finally realised this?
I’m sceptical too but for now this appears to be an actually good move from Nvidia?
