They have constrained supply, which is the foundation for their biggest moat - trust. Importantly, boutique search engines introduce new business models that don’t rely on advertising.
What started as a well-intentioned way to organize the world’s information has turned into a business focusing most of its resources on monetizing clicks to support advertisers rather than focusing on the search experience for people.
