The negative blowback didn't hurt this Simcity launch (yet anyway) for a few reasons. First, so many people had pre-ordered it. Second it was massively hyped up by so many of the gaming sites that bow to the big publishers. Third, it's the next version of the game that will take the big hit from this reputation damage (and EA's brand in general).

By the time it was revealed to be a crappy game, inertia had carried the sales a very far distance.

I've seen this concept play out with eg NBA Live. EA produced a few decent versions of it in the early 2000's, and then produced a few really bad versions of it in a row. The first bad version sold fine, then the next releases sold less and less and the reviews were harsher and harsher.

EA had an opportunity to widen its Simcity base, that's a cost you don't see right now. More people than ever before have powerful desktop PC's. Today I can get a great PC for $600 to $800. Ten years ago, that money didn't go nearly as far (and these are less valuable dollars to boot). EA just burned a lot of casual gamers.
