They need some signal, and metrics are not one of those signals.
The metrics tell you one thing, but how to interpret it requires you to know what people are actually doing. And if you do know that then you don't need the metrics.
Add to that, I don't think I know anyone that could be trusted to not misinterpret the metrics. It is a great way to reinforce what you believe, you can take your gut feeling and finding a way to see it in the data. But that isn't helpful either.
