To respond to your points quickly: I'd rather support a company with a moral stance I agreed with than one that was neutral. I think news media in general has a problem with sensationalism/optimizing-for-clicks/echo chambers, but I don't perceive that Google is particularly bad as an news aggregator. I think a lot of complaints about Google/Youtube overlook that most policy decisions about removals/demonetization are driven not by politics or agendas, but by advertisers, without which Google/Youtube would not exist. (And again, if you disagree and believe that targeted advertising is itself a net bad for the world, oh well.)
Personally, I think viewpoint polarization and the internet's enabling of echo chambers is the biggest problem facing the world. I know Google is often accused of making the problem worse, but I don't agree. Google News, for example, won't stop showing me Fox/Breitbart articles, even though they have to have enough data on me to know I'm super far-left.
Anyway, I did some searching (on Google, ha), but can't find any articles linking Google/Youtube usage to mental health problems, so I'd be interested if I'm wrong. The only one I remember seeing said Youtube had a positive effect on mental health. (https://www.psychalive.org/worst-mental-health-instagram-fac...)
Ah yes. From "Don't be evil" to "Improve the world"? Who asked google to "improve" anything?
> To me, Facebook has no such world-improving aspirations.
Which is why they are being attacked. They are neutral.
> Plus, I keep seeing studies of how increased Facebook usage correlates negatively with peoples' moods
The same applies to google. The more you use youtube/google/google news/etc, the more depress you are. This also translates to news media itself.
> so Zuckerberg's evident goal of "get everyone on Earth on Facebook" feels gross.
Google is even worse. Censorship + agenda peddling + discrimination + google has far stronger monopoly on people's attention and far more information.
No offense, but I wouldn't work for either google or facebook. Both are terrible for society and freedom and mental health.
