It’s interesting to look at the local edits on osm. In my area it’s mostly from Amazon and Lyft, based on proprietary imagery.

There's a few ways for volunteers to trace proprietary imagery and data into OSM with the permission of the owners of the images.

I'm guessing you're talking about private, proprietary imagery?

Yes, some paid mappers use own internal data.
