For context, this question of whether vanilla dark matter models are in conflict with galactic observations has been raging for many years. (It includes both the dwarf galaxy problem mentioned in the article, and things like the "core-cusp" problem concerning the radial dark matter density distribution.) These numerical simulations are fiendishly complicated, and there's always a risk that you just keep adding new tweaks or effects until you get the results you're looking for. I'd be interested in reading a skeptical assessment from the folks on the other side of this question.
