Apple took data from 3rd parties (Yelp, TomTom, and many others) and integrated it all together with their own Maps app.
Google has a lot more features than Apple right now, and a large part of their data is sourced from their own works. Streetview gives them good road data. Local gives them all the data that yelp has (and then some).
Apple's Maps is probably where goole was with maps back in 2007 or 2008.
Are you saying Google doesn't use 3rd party data? Because that would be completely false. Look at the copyright notice in the bottom corner of Google Maps for anywhere outside the US/Canada/UK - around my city the data comes from WhereIs, Sensis, Tele Atlas and GBRMPA as well as Google. Other countries have data from AutoNavi, MapKing, SK M&C, ZENRIN, GISrael, INEGI, and many others.
