I’ve always looked at these systems as “if someone else built this, it would be worse.” Doesn’t the same moral conundrum exist anytime you build a system that dehumanizes people for profit. Ad networks? Drug trials?
Ad networks - people can just disconnect or look away if they like.
Drug trials have benefit to society.
I would argue that creating a system to fire people in an automated fashion when they take too many bathroom breaks like this is morally worse than both of those systems you mentioned.
