Um, that's what Apple is already doing. So far, it isn't working. Google started doing more than that quite some time ago. They even stopped using TomTom / Tele Atlas (one of Apple's bigger third-party data suppliers) in 2009. Does basing a lot of your map data on a source that Google rejected years ago sound like a way to stay competitive? Moreover, one of the things I've seen mapping experts say today is that integrating a variety of data providers can make the maps problem harder instead of easier.
