I still think you're Verizon's customer (or Sprint or AT&T or [insert_carrier]). The Google software comes with the phone, installed by the carrier which makes you a user of Google's software but not their customer.
The carriers are Google's customers directly. Google doesn't care about you as a customer, otherwise you'd be able to get updates on your device directly from Google. You're not receiving anything from Google directly. Google gives Android to the carriers and they receive billions of nano-pennies as the consumer uses the phone, getting ad revenue and tracking customers to their own favored advertisers and service providers.
Android is installed at the pleasure of the carrier to serve their own purpose, namely running a phone customizable to what the carriers want you to see and what they can get paid for. Gradient to Google, you're just a consumer. The big surprise is the carriers haven't returned to the time when they could sell the pictures you took with your phone back to you for 25 cents apiece. Remember the days when they disabled OBEX on their flip phones so they could prevent access to photos and ringtones?
That's what I think, anyway.
