Here’s the thing though from what I heard from talking with people in the industry for years: Back when Steve Jobs was still alive, around 2010, Apple WAS going to make a search engine that would rival Google and in fact would be better than Google, just out of spite because of Android. Jobs wanted nothing to do with Google afterwards, and in fact, wanted to kill and destroy Google, and going after the core, which was the search engine would be the way to do it. And they had zero intention of monetizing it either, it was just a search engine with page ranking and etc and nothing else. It would serve as useful function for the users and it would be what would power Siri.
Plans changed after Jobs died and Apple decided to drop the hammer on this project despite the fact that many wanted to keep this project to preserve and respect Steve Job’s legacy of his hatred toward Google. But if Apple did continued with the project, it would have fundamentally changed the web forever.
