Brave defaults to Google in most countries, but we get paid $0 for it. We also disable auto-suggestions based on key by key tracking to Google as you type your search term, leaving it as an option some users choose to enable.

This isn't that hard (except for doing without the big bucks, which is hard: Brave is building up small revenue to large, not profitable yet -- again, we pay the user >= what we make, 70% of gross revenue for user-private ads, 15% for publisher partnered ads [not yet launched]).
