I'm not familiar with this guy's site so I'm not sure if he means something more nuanced, but "more data beats better algorithms" is too vague a claim to test by picking any number of datapoints. 100 datapoints will of course beat 1,000 datapoints if the former is selected via a random sampling that uses a uniform distribution across the entire population with no response bias and the latter is selected by asking the first 1,000 people you happen to see.
As it happens, I broadly agree with his conclusion (data trumps algorithms), but cherrypicking data-points doesn't provide any evidence for it.
