It seems like the pattern is almost always the same: the ethics team exists quietly in the background, and the only time anyone hears about them is when they either publicly leave the company or start a campaign against it.
So what exactly is the business case? Is it actually worth maintaining an ethics function just to be able to say you have one, when the only time it becomes visible is when it goes against the company publicly? And if this outcome is so predictable, why do companies keep hiring these people in the first place?
