That's an interesting dividing line, and I think also needs to be compared against big companies setting opt-in/out defaults or the "Yes/Maybe later" patterns. What I find curious is that there's been the opportunity for spam for a lot longer, in a way the Win8 live tiles were an evolution of the widgets that first appeared in Vista, and they introduced active wallpaper along with IE4 (or was it Win98?) although that opportunity would have been much less effective as internet availability was much less.
