This article seems a bit dramatic in it's title? People have purchased "blank" RAM for years for the aesthetic of it. I do not personally see the point, but I also don't have motherboards with unpopulated RAM slots. If a company wants to sell a kit that is 50/50, I am not sure that is actually a problem.

This is the computer equivalent of "comfort nuts" for a neutered dog, which is really about the owner, not the dog.
