Their claim: "you have to use maps that are maintained by big companies, only they have the resources to keep the maps accurately updated"

Google Maps: *shows a road over a bridge, with photos, when the bridge was actually destroyed years ago* (and, amusingly, you can see the remnants of the old bridge on the photo taken from the neighboring new bridge)

OpenStreetMap (and therefore OpenTopoMap and OpenSnowMap): *are accurate, doh*
