Thank you for writing, as well as thank you for your contributions to OpenStreetMap.
However, we also don't want to suggest that the street-level data we're showing are actual OpenStreetMap data because, as you will see if you look in detail, that could cause considerable consternation. For that reason we offer a link to the OSM view from anywhere on our map.
To be clear, we carry out considerable pre-processing and some topological simplification of the street network. This includes a lot of re-drawing of routes at the fine scale.
So, we're talking about properly acknowledging derived data. I'd be happy to try to do a better job of that, but maybe another round of your advice or pointers to recommendations would be helpful.
Interestingly, a new version in 2021 will likely be a lot truer to OSM, though with more missing ways rather many re-routed streets.
