The problem is that there's already open-source nvidia driver -- https://nouveau.freedesktop.org https://nouveau.freedesktop.org -- but it's so feature incomplete that it's good only for hobby. You can't run CUDA on it, you can't run any recent games on it, you can run TensorFlow on it, you can't run PyTorch on it, etc etc -- it is essentially useless and has been so for many years.
