Tell me what happens if you run a Windows machine for say 12 months and decide to switch the GPU from NVIDIA to AMD (or vice versa)? Yeah.
In linux it tends to be a nonissue.
When is the last time you used Windows? XP? It hasn't been an issue for decades.
Graphics drivers moved out of kernel space in Windows Vista.
That's true if you buy a Laptop with all drivers preinstalled. But it's absolutely not true if you install on a machine you built yourself.
Linux is significantly easier than it was 20 years ago but still not as easy in general.
