You are completely right.
I do also get why the run these commands is a thing, because it’s usually faster and also is distro / desktop environment agnostic.
Why would someone want to write separate guides for Gnome, KDE, Cinnamon etc. when one or two commands will suffice? But on the flip side, my family and friends will see a scary looking command and immediately be put off.
I feel it’s getting a lot better since more apps are just in the browser or electron apps, there’s way way less to actually configure for most end users. The type of people put off by commands generally won’t go digging through the settings anyway.
I do wish there were a proper GUI for configuring GRUB though. Any that I’ve ever found seemed to fall out of date very quickly.
I wouldn’t really call this a “report” when there aren’t any metrics in the reasoning other than price.
Even in their own article, it mentions how support and updates vary by manufacturer so it’s kind of meaningless to compare iPhone to the whole Android ecosystem. You’d need to choose one or more manufacturer in order to make an apples to apples comparison.
