This is one area I think Linux is really bad on compared to Windows. AMD makes a new graphics card, it pushes out a driver update for Windows and it's all golden.
On Linux? They have to spend months getting it into the kernel release cycle, then wait on distributions to test that update, trickle it down to users and if you're on some kind of LTS distribution you might as well not bother.
You're not entirely wrong, either, though; it's more of a concern with LTS support. Though this is reduced somewhat by most things not actually needing custom drivers by using existing standards, e.g. HID, and/or by userspace drivers.
And, of course, you don't have it at all if you only buy hardware with Linux pre-installed and supported by the vendor. You know, like you do with Windows and Mac.
For all other scenarios, which are most, DKMS has existed for 21 years now.
The Linux distros' approach is superior to Microsoft's in every way. There will always be some Windows-minded types out there who will struggle, maybe they should buy a Mac.
DKMS is not a stable driver API/ABI.
I do know there are others out there, paid "professionals" staffed at some vendors, who struggle with DKMS. But not everyone paid to work with DKMS is necessarily competent by virtue of being paid to do a job.
