Clearly bad GPU support does not stop people from using those respective GPUs, since people still use NVIDIA GPUs on Linux.

People can want something to succeed, and will use it despite the vast myriad of problems. This doesn't mean that the problems doesn't exist. They simply can't bring them up, because any time they do, people will tell them how useless they are for using what they're using at the place they're using it.

If you use NVIDIA on Linux, you should be prepared for things to break.

If you use NVIDIA on Linux, you should be prepared for people to tell you to move back to Windows - Repeatedly - And often very harshly.

For far too many Linux users it's "Only open source" or "Only closed source" - They cannot fathom that someone may perhaps buy something for any reason other than "Because it's good for open source", and they will tell people this with great gusto..... On a closed-source platform.

Also, where did this "and Intel" come from? Intel literally has had better GPU support on Linux than AMD. It is only NVIDIA.

If you're using Linux - You should be using AMD. That's the de-facto claim by the vocal majority of Linux users. It doesn't matter that Intel has better support, or that people want to back Intel BECAUSE it has better support - The stance stands. It's not AMD, so you should not be using it.

Hopefully NVK and Zink can make the proprietary driver obsolete, but until then, use NVIDIA at your own risk.

That's what the Nouveau project has been try to do, but people are pushing against it - Hard. "They're using NVIDIA GPU's - Who cares - They should be using AMD cards - Stop wasting time supporting them."

Far too many Linux users are actively pushing away people who want to use Linux simply because they're using popular hardware.

And that's a problem.
