As said i have contacted the author (primarily regarding attribution - 
which he promised to improve - and has partly already done).  I also 
mentioned the share-alike issue - but the author thinks this is fine as 
it is and i am not really in a position to claim it is not.  He also 
said he cannot provide the Google roads data itself since the Google 
terms do not allow this (obviously).

Part of the problem is also they are using Google Earth Engine - which i 
am not familiar with and which probably makes many of the data 
processing steps fairly opaque so the authors might not be fully aware 
of what actually happens in detail 'under the hood'.

I suppose if you pressure the authors into providing more intermediate 
data you might get separate raster maps for the OSM roads and the 
Google roads.
