For those not aware, Google is rolling out their new AI-based "Generative AI" search, which seems to mesh Bard with the standard experience.
I asked it today why Google no longer follows their "don't be evil" motto... The results are pretty hilarious.
But this phrase was intentionally about what they claim to not be.
It's a good approach when it's well intentioned, because instead of encouraging an action, it discourages one.
"Be a good person" dogma can be used to justify a lot of things. "Don't be an asshole" is much more limited in how it can be abused.
