Google never used OSM intensively. Apple has in some regions, but I’m not sure how it has evolved over the years.

They have a team of employees working on the app and the hosting of servers to package the data in downloadable files also costs money. So consider donating if you don’t want to use the Play version.

While I have seen anecdotal evidence for GMaps monitoring chabges in OSM to keep their data up to date, the only “filling in of Gmaps with OSM” I’m aware of is where they used a government dataset that itself was using the OSM license.

What’s your point?

Because if ya ain’t white, you can’t be free!
