I'm more of a technologist than a product guy so I care more about the technologies coming out of Google. When I see major open source efforts like tensorflow or k8s I see goodwill and trust. Outside the realm of software, when I see principles or ideas or algorithms like CoDel, BBR congestion control, and SPDY (later becoming HTTP/2) and even later QUIC, MASQUE, I see the same (please excuse me for listing networking technologies because that's where my recent interests are). Here's a very simple thought experiment: if all the above technologies came from a different company say Cloudflare would you consider these earning them trust? The answer is an unequivocal yes.

The only reason why you might be unable to name a single thing Google did to earn them trust is perhaps because of rampant brainwashing by the anti-Google rhetoric.
