The site is missing attribution, then, which is required by OSM's license (see https://www.openstreetmap.org/copyright )

Came here to say this - looks awfully like OSM data and no attribution.

I'm also not clear on whether Google likes displaying OSM data on their map; it's a strange combination. I can't ever remember seeing "Copyright Google, Copyright OpenStreetMap contributors" in the footer of a page.
