It sounds like TT will be a net taker from OSM, I hope they contribute as much as they benefit, as otherwise it would sound like they're giving up on prop-mapping by cutting costs. It's a press release I suppose, but saying the world lacks an open platform, and processing to use such open platform, sounds a bit weird
Tom Tom have got their work cut out, this space is super competitive. Just passively taking the data is not a way to compete in this space. You need to step up to stand out. Tom Tom is doing this out of necessity. They've been active in this space for a long time but they are now getting a lot of competition from other companies; many of whom are pooling resources via open data efforts, like open street maps. That gives these companies a cost advantage because maintaining maps is an expensive business and the base map is now a free commodity.
