Agreed. I have a Linux computer upstairs, and the Wifi dongle (I know, but it's fine!) broke. Buying a new one, or even knowing what to buy, that doesn't require me to USB key some random drivers (probably cloned off GitHub) is a tricky task.
I have a mix of systems, have had for several decades, Linux works on all of them, old and new, no issues, seems odd what you're saying, almost like it was entirely made up.
It goes without saying that your experience is completely irrelevant, unless you can prove that you had my hardware working out of the box on one of those devices.
Have a look at this simple tutorial[0]. Compare it to "plug it in" on Windows.
Without reading your link yet, I don't understand why is it difficult to understand when I say all my devices on all the Dell (and Alienware), HP and Lenovo PC's I've bought the past two decades just work on Linux.
