When you think of money as “intermediary token of value”, this makes a lot of sense. If you have a love of money, you will naturally tend towards whatever has the highest money-in-to-value-out ratio. With Google, however, the user is the product, so Google only want to put as much value in as to make sure the user stays. And yes, that does result in a good and polished browser, but only because it’s what keeps users from going to another one.
