In my opinion, most old-school MMOers pine for the good old days for a much less nefarious reason: They 
liked having more options. Put another way, the gameplay was simply more diverse, and that has nothing to do with filtering anyone out. <. . .>  
MMOs are -- or used to be -- virtual worlds; <. . .>  Unfortunately, complexity, commitment, and immersion are four-letter words to the new breed of MMO player, and as a result, 
developers are following the money towards simplicity and missing features (wherefore art thou housing, crafting, and really any sort of gameplay that doesn't revolve around heavily instanced homicide).
