This is where DuckDuckGo’s Knowledge panel-like breakout box on the right rail with important details like name, address, phone number, website, etc., are drawn from, including Wikipedia.
DuckDuckGo also pulls information from user-review site Yelp, including reviews, addresses, phone numbers, and business hours for that panel as well.
Business-location directions are now provided exclusively by Apple Maps, a change from prior to 2019 when DDG defaulted to Bing Map.

please feel free to correct me with technical documentation that shows ddg uses Google at the core.
