I thought their mission statement was "Don't be evil", until they shortened it for practicality to just "Be evil". It's certainly how they've been behaving in recent years.

It's now "Don't be evil*"

* Subject to terms and conditions, lack of evil not be available in all regions.

That wasn't ever a mission statement, and fwiw it was in the employee handbook still in 2023 when I got laid off.

They changed it more than ten years ago into "Do the right thing".

I like "Don't be evil" better. It inherently acknowledges their position of power in a way that "do the right thing" hides

Motto, not mission statement.
