Yeah, I'm sure it's braindead simple if you regularly do systems stuff on Linux, like I used to. But not having done that for a while, I needed to a) find the info for the different ways to install the driver on this distro and figure out which one applies, b) figure out which specific driver version you need, c) install it and then figure out which of the few dozen other packages in that repository you need to install, d) manually blacklist the nouveau driver which it inexplicably still tries to load, e) reboot which automatically bookts into MOK utils which asks you for a password and seemingly doesn't accept anything you enter, f) figure out how to re-run MOK Utils on boot to enroll the module, g) futz around setting the MOK Utils password until you're about to throw your computer out the window, h) figure out that the utility doesn't work with non-querty keyboard layouts, i) have to re-enroll every time the driver updates.

Sure, it might be simple as far as Linux administration tasks go, but I'm not using Linux because I like dickering around with Linux-- I need a POSIX system that supports my hardware to use as a professional tool. Regardless of whether or not it's a fair comparison, my comparison is to the experience with Windows and MacOS. It's not a judgement of the competence of the people that made it or the overall product quality-- it's apples to oranges. Unfortunately, it's Apples-to-Oranges for a lot of UX and QoL factors as well.
