If Google used the OSM data, they'd risk being forced to share their mapping data - OSM is distributed under a share and share-a-like style license. There are probably ways around it, but Google regards their map data as being core to their business & they've spent $billions on it. There's no way they're going to risk that. Apple is using OSM data from before the change to the new licence if theirs is from 2010. Google could do the same, but what would be the point?
