I don't think you, or they, have any idea how often people use them.

that's nice ;)
I can confirm, many Users i observed feel safer with using scrollbars.
Also, with the mouse wheel, the larger the page is, the slower scrolling becomes, compared to using a scrolling interface that allows navigating the entire page with one gesture.
In other words: Users often prefer scrollbars, since the scrollwheel would mean "scroll, scroll, scroll, scroll, scroll..." which can go on forever on large pages, while with the scrollbar it's always "aim-click-drag-release".

That's what KDE does. But it goes against the principle of parsimony:
having two similarly accessible methods of doing the same thing slows
people down, by making them dither. (For example, it's okay to have a
title bar close button and a "Close" menu item, but having two close
buttons is bad. Similarly, having two scroll-up buttons would be bad.)

yes, i remember okham's razor, parsimony is a great term in this context.
We also speak of "the path of the water" sometimes in different domains, e.g. military strategy or social theories.

People will pick the easiest way, and confronted with many, they might get confused initially.
But the learning time is short, considering that the icons are not similar but truely identical.

It's a question of comfort, and i can imagine it to be much more convenient to have redundant scrollbar steppers, and to have the ones on the bottom together.

In the larger software suites i use for audio engineering, scrollbar steppers are close to zoomcontrols, or even function as zoomcontrols when dragged.
This is a major challenge for each competitor in the sector of audio engineering suites, since overview, pan, zoom, content navigation are the most frequently used features, even before all the edit features. In a busy day, you might lose up to an hour to poor interaction design in this area.

I am quite confident that the current direction of Ubuntu will give it a great UI, that can easily compete with the IxD of the professional software suites out there..
