That said, Apple should have written a big fat check to a company with much better data. (I still think Apple needed their own mapping and apparently maps improve as more users use them.)
When iOS 6 was first available, I hit a link to a restaurant on a web site that opened Maps to the restaurant's supposed location. The location it opened actually had the restaurant's exact, correct, latitude and longitude. But Maps decided it knew better and showed me where it thought the restaurant with that name was, which was about a half mile off. If I removed the name and left the lat/lon then it was correct.
Or just search for "emergency room" and notice how, even today, it still shows tons of medical stuff but no actual emergency rooms.
