> You have that backwards, at least for some companies

Absolutely I do - my overall (and apparently poorly communicated) point was more about Apple pulling in data from OSM to improve their product. They (and others) do contribute back, I only meant it's hardly coincidental that OSM and Apple Maps improved around the same time.

> I've never seen any cite for Google contributing their data to OSM.

This is what I'm so up-in-arms about: people spend so much time adding to Google Maps for free (not even necessarily via OSM), to be locked away behind paid (past a limit) API calls. Perhaps I should have been more explicit in that many companies contribute back, and Google being an outlier in that.
