In earlier articles the "quality" of the song was in fact accounted for - if a song did better in the semi finals than its position within the network of countries giving each other points by default warranted, it was considered to be a better song.

That said, while the predictions had Sweden on top, it also had Norway in third place. Obviously the effect of a song being good isn't as strong as this model thinks. The top three had two countries that have lots of friends, Russia and Serbia, that had not-too-terrible songs that therefore managed to scrape away points even from countries that aren't friends.
