I agree -- the maps look great. https://next.duckduckgo.com/?q=restaurants+in+boston.

There might be some complaints/confusion about attribution from the OSM community, but overall really happy to see a major search engine use OSM maps!

It does. Click the "i" button: Map data © OpenStreetMap contributors, CC-BY-SA

That's not on-map, that's hidden behind a click. osm.org/copyright makes it very clear that the attribution needs to be on-map. You don't see Google permitting people to hide their brand away like that!

Apple does this too in all of their uses of OSM in their maps.

There is some OSM community discussion on the UX behind this here: http://www.openstreetmap.org/user/lxbarth/diary/21769

Apple's maps are not just OpenStreetMap - there's a lot of other data sources in it too.

For the OSM data Apple do use, I think it's quite old OSM data from 2010-2011 or something. As far as I remember, they used that because the license changed after that, so I believe that's under different terms.

You should rant about runkeeper too, as they do the same thing by hiding the OSM contributor information.

Doctor_Fegg makes a good point. The OSM Legal FAQ states: "For a browsable electronic map (e.g. embedded in a web page or mobile phone application), the credit should appear in the corner of the map, as commonly seen with map APIs/libraries such as Google Maps."
