What ever makes you feel better. The attitude towards Nvidia is toxic considering some people need it for work and other people just don't have the choice to switch.
The Nvidia open source drivers are provided by Nvidia and the nvk project is built referencing that code. Nvidia itself has helped in their weird way by providing stuff like headers for the 3D acceleration and compute hardware to giving nouveau access to the GSP firmware blobs. These new drivers would be near impossible without a little help from Nvidia.
It's really hard to ask a company that makes a shitload on quatro cards to just give up the source code when pretty much the only difference between quartos and rt cards comes down to software locks and slightly higher quality silicon.
