Do they actually not like their users?

Hmmm...  I don't leave my TV on all the time, and yet, I benefit from OSD to program my time
on my VCR.  I only need to do it twice a year and it only takes a minute or two.

Using menus on a screen that are readable and intuitive compared to the tiny buttons and
limited feedback pre-OSD VCRs gave me years ago is a UI benefit.  You could compare this to
right clicking the background vs. having to edit an .xsession file and adding an xsetroot
command in the right place pointing to a graphics file of the right format.
