Le duh. The whole point is that the perfectly true data is misleading and uninformative, and the "ground truth usage data" argument has a plot hole.

It's not that it has no value at all, it's just that it's stupid to know one thing (how to collect usage data) and think that is all you need to know and that that obviates all other sources of understanding.

If you wish to collect money from human customers, you have to be some minimum level of human yourself. Talking to your customers is not some icky hardship to be avoided and replaced with nice bash script.
