What if your plumber installed a camera in your bathroom for informed support decisions? Sure would be useful for him to see where you put those "biodegradable" baby wipes after the deed.
Here's what I think would be a closer analogy to what's actually being proposed: the water company installs a smart meter allowing them to read usage data more frequently. They randomly sample 2% of customers' data and prepare a histogram showing the top daily usage hours and total usage over a monthly period.
