Lots of stuff have Win/Mac only drivers.
Most stuff in my field of multimedia, from top notch quality items available for other platforms (Apogee stuff, UAD Apollo, Black Magic Cinema camera) to prosumer products, including many consumer stuff which only have some community drivers that don't let you use all the functionality.
I think you might be misunderstanding the claim that is being made.
That's barebones basic stuff. Of course that should work out of the box...
It's all the other stuff driver-wise that matters...
I don't think anybody has ever claimed that linux has good support for specialist multi-media hardware.
The parallel to your argument is that people should blame Apple for random third-party hardware not working out of the box with OSX.
No they shouldn't blame Apple.
But they should give minus points to OS X for "compatibility" when "random third-party hardware does not work out of the box" with it.
And similarly: they should not "blame" Linux for "random third-party hardware not working out of the box" with it, but they should give minus points to Linux in the compatibility department.
Support for third party stuff is what makes for "great driver support".
Or back when I was in neurology, there was EEG hardware for Win and Lin, but no mac.
I mean, you're responding to "Use lenovo as a reference model" with "looking at a bunch of other suppliers from a niche industry, it doesn't match up". It's not just apples and oranges, it's not even the same ballpark.
When people talk about OSX hardware support they tend to talk about depth, Windows or OSX is more breadth.
Though the depth of OSX's hardware support is debatable as well, GPU support has historically been fairly dismal.
This was a stupid article. "Gee, water is wet and sand is dry! (usually)"
