The open source solutions aren't good because validating and fixing this data is very time consuming (read: expensive) and carried legal liability (read: expensive). Open source tends to not be good at requiring many people to do tedious things (see: most open source documentation). Companies could pay people to do it but then you've recreated a commercial vendor except competitors who don't pay get a benefit. Companies tend to open source things which are not direct competitive advantages for others in the same industry while this would be exactly that.
