Not much if decisions are made with good intent and good reasons. From time to time, mistakes will be made and those usually result in public outcry and/or fines (regulations are good tools). Google isn't a perfect company and I get that part.
Google's had some external and internal issues put out in the air lately. Such as an engineer who put out a doc which could have used an editor (https://assets.documentcloud.org/documents/3914586/Googles-Ideological-Echo-Chamber.pdf), which got him fired in the end. Google pushing out a person from a think thank who was critical of Google's policies. Just a few that I can remember right now. Are these a pattern of removing critical people and for what goal?
Antitrust issues too because of someone being critical/being cautious? (https://vivaldi.com/blog/google-return-to-not-being-evil/) We gotta do what we gotta do to stay competitive, but what is the reason for this? Why bother with critics?
I guess we will see in the upcoming months what direction Google is taking if the stories pick up or not.
