I take that to mean "all PBF isn't equal".
There are reasons I am asking.
For example, if I wanted to license content from opentilemaps.com . . .
I couldn't do it online, because they don't use an Arcgis server to host as far as I know.
I couldn't do it offline, because they don't provide it in .vtpk format.
We question whether we are a large enough business to recreate a worldwide map like openmaptiles.com.
So we would need to find a tile vendor that is a loyal ArcGIS user.
OR
Figure out the cost of hiring people and servers to recreate a tiled map from OpenStreetMap data.
What are the ArcGIS Vector Basemaps missing? Contours, for one thing. Hiking and walking trails, for another. These two things are very important to my user base.
