Weak business and POI data
“OSM is great as a map, but the biggest thing keeping me from switching from Google Maps to any OSM solution is the "white pages"”
Comment from 7 Jul 2026 in “CoMaps – FOSS Offline Maps” “This is more about OSM than Organic Maps, and I agree that looking for businesses it's not great.”
Comment from 5 Jul 2026 in “Organic Maps” “I am a big fan of OSM, but modern maps are not about street names and building, but about POI.”

Comment from 2 Nov 2025 on Hacker News “They also often include "pairs" of lighthouses (high / low, front / rear) where newer ones have replaced older ones”
Comment from 4 Oct 2026 in “A map of every lighthouse” “OSM has a defined canoe=yes/no tag, but it’s supposed to be used for legal access, not navigability.”
Comment from 3 Aug 2026 in “Why Book Corners won't sync contributions back to OpenStreetMap” - Comment from 7 Jul 2026 in “StreetComplete: Fixing OpenStreetMap, one tiny quest at a time”
Lacking accessibility and sidewalk data

Comment from 31 Aug 2026 in “I attended the State of the Map conference” “accessibility-related data ( especially especially crosswalk info) is apparently sorely lacking in OSM”
