What? There's nothing being said about simcity, or what it "teaches".

The whole article is about using simcity as a (distorted) reflection of reality. (And that reality may be tending towards sim city's outcome).

This is not even close to an accusation that city planners have learned poor city design by playing simcity

The linked article is not criticizing SimCity. This is an architecture student who made something unusual with it, and finds a hidden meaning in his project. Nobody is saying that SimCity teaches bad lessons (at least not in this article).
