Not the OP, but I'd much rather contribute that information to OpenStreetMap so that it's freely available to anyone who wants to use it (including Google!).
Google's data is copyrighted and open street maps is not per their policy "If you alter or build upon our data, you may distribute the result only under the same licence" [0]. They even mention google maps in their privacy policy: "OSM contributors are reminded never to add data from any copyrighted sources (e.g. Google Maps or printed maps) without explicit permission from the copyright holders."
So no they cannot use it and a quick search looks like apple still relies on Tomtom which is also copyrighted [1] and thus they cannot use it either.
