It breaks the terms of the Google Maps & terms of the Google Maps API.
you might want to google 'google maps wms' (2nd one down)
pleased don't copy data from Google Maps into OSM.

VectorMap is in GML - https://www.ordnancesurveyvectormap.com/howItWorks/
OS VectorMap™ Local is a national vector dataset supplied in Geography Markup Language (GML). It has been derived from OS Landplan data and has been generalised to view between scales of 1:3000 to 1:20,000.
It is cleaner and better than Meridian2 (fake roads!)
But agree that Meridian2 as background raster/trace is worthy of implementation especially for rural areas of England, Scotland & Wales.
But OSM data should persevered as is and not replaced by it.
suggest at Road Name checking comparison option?
