We've successfully integrated tile services into Tableau as alternatives to the Mapbox defaults. I understand that the latest version of the software includes significant improvements to the mapping capabilities, but there's still quite a gap between this "casual mapping" and what's possible in software like Pro.
I've spoken with many colleagues in the data industry about whether supporting Tableau as a platform would be a good idea. The consensus, which I agree with, is that while Tableau is not "cheap software", users tend not to spend more than their software investment on data… the opposite of what we find in the GIS world. This may well change though.
