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.
