DuckDuckGo allows for supplement of Google Search, as does Brave, and other search engines. Google freaked out after the ChatGPT release (rightly so) and padded their hand a bit.
Impact would probably be Ads via Google Search Engine. Which, great, because Google Ads-generated results remain a huge vulnerability in terms of active phishing attacks. Maybe it's gotten better in the last month, however I don't really use Google Search anymore, to avoid phishing attacks.
And, this is one reason why I like Brave, because I can control what content cannot appear in my search results, to better mitigate phishing attacks.
