I respect your choice, but I think it's unfair in this case specifically (but in many other cases too) to say it's about 'pretty' and 'better advertising'.

I read a lot on my mac, and I love the lack of scrollbar. It's one less 'element' on my reading experience (similar to almost all ebook readers not having chrome, like scrollbars and page numbers, or hiding chrome unless specifically requested). And because of how integral and 'decent' using the touchpad is (two finger scroll), I automatically scroll briefly to show the scrollbar in those few instances where I care about what position on the page I'm at.

Of course, that's just one example, but I know many others who feel similarly. 'Apple knows best' doesn't just mean marketing and pretty, it often means decent choices that are good for a large percentage of people, and yes, you have to accept that.

I find apple does do a lot of stuff that doesn't work for me. Even the lack scroll bars I rather hate when I use Finder (and don't get me started on that!). I use an android phone for that very reason.

I don't always like the choices that apple makes for me, and I might reach a point where I opt out completely. I'm just saying that in this case I think apple made a risky but decent choice, that wasn't just about 'pretty' or 'marketing'.
