I don't think Google provided much revenue in 2016; Yahoo was the search provider in the U.S. Mozilla is not tied to Google.

I wouldn't consider Yahoo much better than Google either though...

google was the default search engine in the rest of the world where it has the most market share except maybe Russia, also this was a move by yahoo in order to help with selling their business at a non negative price tag.

Google stopped paying Mozilla for that as their global deal expired and Mozilla signed with Yahoo.
