A metric is a proxy, always. Even for sales. If the sales increase but the satisfaction of the users decreases, that's not necessarily good.
IMO, the worst thing one can do with a metric is believe that it is subjective. Give me a metric, I will optimise for it.
Doesn't mean that having metrics is useless. It's just important to understand what they mean.
