Thanks for your response.  I can understand how having your changeset reverted is upsetting.  However, I checked and I did revert the correct changeset, one that cited "Google Maps" as its source.  This isn't about "copyright" but rather contract law.  When you accessed Google Maps, you agreed to their Terms of Service, which is a type of contract.  By violating that contract you put not only yourself but the OpenStreetMap project and users of OpenStreetMap data at risk.  The fact that some acceptable source exists to support your edit is irrelevant, you clearly copied from Google Maps in making the edit as that is the source you had cited.  I will once again be reverting the edit.  If you want to redo the edit using only an acceptable source and redo it from scratch (not just reverting my revert) that is fine - just don't use, cite, or reference Google Maps or any other source that is not acceptable.
