Lots of global companies use OpenStreetMap. Take Strava, for example:

The Strava Global Heat map shows cycling activity around the world, including Christchurch. ( https://labs.strava.com/heatmap/#12.00/172.58547/-43.50785/hot/ride ).

The road lines are based on OpenStreetMap ( https://medium.com/strava-engineering/get-on-the-map-dca5d2693c37 ).

By improving OpenStreetMap we can ensure that our fellow citizens are making decisions based on accurate information provided through 3rd-party providers.
