> Turns out it was just hiding it because scrollbars were entirely hidden and disabled by default
They are if you use the touchpad, and appear whenever you scroll. The logic is that as you are scrolling with the touchpad, you will not click on the scrollbar, so in that case it is a useless appendage.
> Then there's the fact that the editing keys don't work at all consistently or correctly (and sometimes just don't work at all)
I am not sure what you mean by “editing keys”, but Apple takes painstaking effort to make sure most shortcuts are global, and in text entry fields, Emacs shortcuts always work.
> And nowadays they like to hide functionality behind obscure multi-finger touchpad gestures.
Sorry but this is just a laughable complaint. Apple’s touchpad and accompanying gestures are considered best-in-class and have been so for more than a decade. Microsoft and various Linux distributions have tried to catch up during that decade+ and still aren’t close.
There are many things one can complain about with macOS ever since Lion started the iOS-ification, and I’d be right with you, but saying the old Mac OS X UI was lower standards than Windows 95 (and I assume XP) is a supremely contrarian statement that few people of that era would have made.
