However, geography_10m.geojson also displays “©2023 Tom Tom” (lower right corner) and links to Microsoft (corporate logo) and azuremaps dot com (smily face in square). Huh? Are the data (the 7 MB of geojson, say) copyrighted or only the presentation of the map?

You’re looking at GitHub’s preview of the GeoJSON file. This copyright notice pertains to the basemap, not the GeoJSON data. Last year, GitHub switched its GeoJSON previews from an OSM-based Mapbox map to a TomTom-based Microsoft Azure map. (GitHub is owned by Microsoft.)
