I have a hunch that the reason for the excessive space is that it is much easier to make it look good. I'm really good with frontend, but I only have quite limited design training. I can whip out a good non-dense layout pretty quickly. On the other hand, pretty much every (good) information-dense layouts I ever worked with had to be properly designed by a professional. Maybe the reason for that is just fashion, I'm constantly informed by what I see and it's easier to replicate, whereas something that "breaks the rules" needs a better professional.
