My two cents on paid search engines: yes so much awareness around privacy these days. so there might be a potential shift in user behavior, which opens up a big market. however, i am skeptical because people are used to free search engine that surfaces good results.
so privacy is great value prop. but not so much that i am willing to pay for it while living with worse search quality.
