Frankly, and not to flame any side, my take is the trope is clear and true simply by analyzing the money flows.
Who is paying for what.
Who Google is paid by.
We indeed are the product sold by Google to its customers.
Now, obviously Google needs to catch us first, and for free, so, as their business is definitely very lucrative, they hire a number of good designers that build a very good interface that seduce us, good and efficient ways to register easily, etc.
In this sense they indeed are somehow innovators : they drove the competition to better products.
But this doesn't remove the fact Google customers are definitely not us.
