This appears to be based on a misunderstanding; the OSM project isn't an app released by a company, instead it's a global community creating a map dataset, somewhat similar to Wikipedia.
If the data in your country or local area isn't good, then please consider becoming a contributor to OSM and edit the map. By making the OSM better, you can help solve those consistency problems and improve the experience for the growing number of people who are using it - whether directly or via companies like DoubleMap.
Being a contributor is nice and fuzzy, but not a commercially viable option. If my customer says "I can't find this town on the map", I'm hardly going to tell them to drive out and map it themselves.
