Apple Maps pulls in OpenStreetMaps data in my area of the country, so submitting information on OSM means an eventual Apple Maps upgrade for me. I edited the 3D shape of some of the houses in my neighborhood and added missing streets on OSM and saw them imported into Apple Maps a few months later.

Here is a map to see where people affiliated with apple are contributing to openstreetmap: https://piebro.github.io/openstreetmap-statistics/#e19b it seems they use OSM data everywhere but in North America and most of Europe.

Apple Maps also credits TomTom as a data source, so could it be OSM > TomTom > Apple in terms of the data flow?

Accorinding to wikipedia they have many different sources (https://en.wikipedia.org/wiki/Apple_Maps#Features):

> The main provider of map data is TomTom, but data is also supplied by Automotive Navigation Data, Getchee, Hexagon AB, IGN, Increment P, Intermap Technologies, LeadDog, MDA Information Systems, OpenStreetMap, and Waze.
