I wouldn't consider "Stop what you're doing or we will end you" a slap on the wrist.
My guess is the app would have been removed from the store. Uber was able to get away with just a warning.
There have been countless posts on HN from smaller devs getting their apps immediately pulled upon an update review for something they got no warning for.
Uber actively tried to deceive the review team.
Doesn't this simply teach would-be bad actors that they get to act with impunity until they get caught, and then simply stop?
