There’s no attribution that I can see on the second embedded map on the page (on mobile). A honking great Radar logo, but no OSM attribution.

This trend of “our branding takes priority over the required attribution for the free map data we’re using, but hey, they’re a little nonprofit so can’t afford to sue us” really ticks me off. Mapbox started it as a calculated move, and since then others have followed claiming it’s “the standard”.

But in this case I’ll assume good faith for now and hope it’s fixed. A simple “© OSM” would be fine.
