Google Maps gave incorrect routing advice resulting (on their part) in a person's death. It was a decade out of date, it had been brought to their attention and they did nothing. They still used that data in their routing. Obviously they have some sort of responsibility here imo.
There are hundreds of sources for map data and I bet you most of them aren't up to date.
Idk why you think I'd think differently if it was some other company, routing provider etc. If it was a municipal roadside map that showed that you're free to drive off that bridge then it would be the same. Or even a private roadside tourism map.
