Gabriel Weinberg, the founder and CEO of privacy-based search engine DuckDuckGo, , called for privacy legislation in the United States during a hearing on GDPR and CCPA before the Senate Judiciary Committee, declared, “Privacy legislation is not anti-advertising. Take our business for example: When you type in a search on DuckDuckGo, we simply show you ads related to that search. If you search for ‘car’, we show you car ads. But those ads won’t follow you around, because we don’t know who you are, where you’ve been, or where you go. It’s contextual advertising versus behavioral advertising.”
