This is very, VERY subjective. Even if Google did something like "you pay $7.44 per month more than the average Comcast customer in your area" there will be very similar posts detailing how 'Google reads your monthly payment data'.
My point was just that Google gets and (probably) analyzes aggregate payment information but the user only gets what they already know. If Google is sucking up all of that data, they could at least give some insights to users too.
Now I'm curious to know if they're using this info to analyze competitor marketshare and/or set prices for competing services.
We already know they do... They'll even milk companies for money, bet against them, etc. It's clearly they should have their company broken up IMO (and I'm typically a libertarian)
