OSM editors are prevented from using Google Maps because OSM prefers that we have explicit permission to use data sources. Since we don't have explicit permission to use Google Maps, we can't use it.
Separately, Google Maps has a terms of use that prevent reuse of Google Maps data. You agree to those terms when visiting Google Maps or using Google Maps API.
You wouldn't be breaking copyright law when copying from Google Maps to OSM, you'd be breaking the terms of use contract with Google and community Norma expectations in OSM.
