it's wrong answer actually based on user comments it scraped since it was a trending news when they changed code of conduct. news were actually fake and about 99 percent internet users are it up. in reality they didn't remove the "don't be evil". they moved it from top of the code of conduct to end of the code of conduct.
There's really no substitute for expert knowledge for content. The LLMs are simply going to speed up the negative feedback loop, exactly as you suspect. GIGO at its finest.
In a way it might turn out to be a good thing for the internet because it will force us all to reevaluate the rest we produce and consume online content.
It wasn't moved, the opening and closing sentences had don't be evil, they removed the preface paragraph at the top, but left they closing sentence.
“Preface
Don’t be evil.” Googlers generally apply those words to how we serve our users. But “Don’t be evil” is much more than that. Yes, it’s about providing our users unbiased access to information, focusing on their needs and giving them the best products and services that we can. But it’s also about doing the right thing more generally – following the law, acting honorably, and treating co-workers with courtesy and respect.
The Google Code of Conduct is one of the ways we put “Don’t be evil” into practice.”
Closing sentence:
And remember… don’t be evil, and if you see something that you think isn’t right – speak up!
The closing sentence that remains doesn't carry much weight without the preface.
