[OSM-legal-talk] map drawn based on OSM tiles

In my mind, the tile license (CC-BY-SA) sits on top of the database
license, as the license to a produced work by the OSMF. So if what is
extracted is solely what was in the database, then the extraction is not
material that the tile license covered (the tile license cannot actually
change the license of the data, which is ODbL, as that would be
impermissible under ODbL). This is the same principle, that if you use a
CC-BY song in a music video that is licensed as CC-BY-SA, and then someone
comes along and rips the song from the music video, the song is still
CC-BY, not CC-BY-SA.
Thus, assuming the shapefiles are essentially the equivalent of simplified
OSM border shapefiles, the shapefiles are covered by ODbL.
Now, it sounds like you're not tracing very much, so it's possible that you
have traced fewer than 100 features in which case your tracing is
