Probably just a question of aesthetics. A lack of ads is NEVER a problem. People looking at a glance care that the spacing/font/other visual elements are visually pleasing. That does not require a retina burning white background, since I prefer dark color schemes too. You don't need to go as far as a bootstrap variant like I use, but there is something to be said for hand editing your CSS to give things a nice look.
