That's a fallacy of datamining. More data does not equate better algorithms, it equates more false positives.
As an extreme example, imagine using just random data. Any pattern you look for will occur sooner or later in pure random data. The rarity of the pattern is offset by the amount of data you generate. More data -> more patterns. That doesn't mean the incidence of the real thing increased at all.
