I have the opposite perspective actually. He accidentally made something fun that a lot of people enjoyed, and instead of letting them run with it he closed it down out of, essentially, pique because he thought those people were having fun wrong.
It was always an absurdist demonstrative to prove a point about the hazards that the game industry would soon be forced to confront.
It is now so apparent how shamelessly game developers will exploit human psychology instead of pursuing actual fun.. so it's not as useful of a warning.
Not all fun things are equal however, otherwise you'd have to classify taking drugs and directly supplementing "fun" hormones as the best entertainment in existence.
