Probably depends on the use-case: I mean, weren't the cryptocurrency people using AMD before they switched to custom FPGAs? But for sure, for the TensorFlow users, there doesn't seem to be a viable alternative to NVIDIA and there must be a reason why CUDA is more popular than OpenCL.
What I mean with ignoring consumer wishes is that they neither offer an open-source driver like AMD and Intel do and they do not even support others in doing so, like the Nouveau people. Subsequently, as a Linux user with NVIDIA hardware, you are either stuck with the buggy binary driver or the feature-incomplete Nouveau driver while AMD and Intel users have relatively stable and feature complete open-source drivers.
Why do you think Linus Torvalds likes Nvidia so much?
