They didn't drop it. It was still in the handbook in 2022 when I signed it.
People like to claim they dropped it: but it's still there.
Now since I was laid off in the mass 2023 wave I can't speak to it's current state but I'd be shocked if they removed it.
My guy I literally worked there and signed the employee handbook. Don't Be Evil was right before you signed if I remember right. Regardless: it is 100% in the handbook.
