Where do you get this idea that it was free to Nokia? It makes no business sense for Navteq even if it's 100% Nokia owned to give them the data for free. They need to show a profit on their books. So they licensed it to them. Probably at a reduced rate but still there was cost.

I know we charge our parent company for using software that we host and maintain. It's plain business sense. It takes our time, effort and resources to maintain.
