Some people probably think "nobody uses Bing", but Bing powers a lot of different search engines (Yahoo, Ecosia, AOL, DuckDuckGo, and more). It's the default search engine on millions of devices (Windows, and even if you change it, Windows search still uses it; Xbox uses it as well.)
I hope Microsoft has a good write up on how this happened, both on the search term blanket ban and the safe search results thing.
