Selling "Customers as a service" is the big, new economy and every single "startup" and "app" coming out of places like Y Combinator in the past few years has been about nothing more than selling your information. Every mobile app, every mobile game. Every "CHECK OUT THIS FREE NEW THING!" For example, Life 360. Think they're offering this for free? Life360 is currently valued at $250M. Facebook paid a few billion for WhatsApp Messenger.
You're a complete moron if you haven't been watching this.
