Huh? Safari is just a portal to the web, to websites. Google is already serving ad on websites. 🤷🏻♂️How will Google collect the 18B if Apple remvoes Google as the default search engine and makes Bing or DuckDuckGo as the default? Even I am interested to know this. I am pretty sure even Google would like to know this too so that they can save the $18b per year fee.
Search is for collecting data, not for serving ad.
