Google restricts use of Map Maker data to non-commercial use. OpenStreetMap allows commercial use.
The other restriction is that Map Maker data can not be used for any service that might compete with Google.
This licensing difference makes the two data sources incompatible. If
Google removed the commercial use restriction and others, there would be no
problem is using both data sets together.
I suppose this is understandable, as Google is a very large company with commercial interests they are trying to defend.
OSM
has a very different aim, to produce data in the commons, available to
all. We think this kind of data is too important to restrict to any
particular usage.
