Safari is the only real opposition to Google based browsers at the moment. Yes Firefox is a contender, but it has no brand traction among non-power users. Google has the brand, Safari has the defaults and energy efficiencies of the growing Apple laptop/desktop market. Although not open source, I trust it far more that a Google based browser as Apple - aside from PWAs competing with their App Store - has no real incentive to commodify, restrict or surveil the web like Google does.
