What my experience has taught me is that you have these 80% things that are good, but there is the one person or thing that ruins it for everyone. One person, one manager or CEO who pushes something through because he wants some gain, or one selfish move that is born out of short term profit or thinking.
From climate change, to wars, to ill-willed software, history sometimes get bend by those bad decisions sometimes stemming from a comparatively small but powerful group who yield too much power. Google is for all purposes a monopoly which makes all their decisions at least suspect since they aren’t competing on the same level as a Mozilla, or name any other search engine. This is bad for any ecosystem.
I wish I was still seeing the early Google that was optimistic, people focused, approachable, but that time is at least some years in the past. There are probably good people working for Google still with that ethos, but it gets overshadowed by those nagging decisions that are suspect.
