Most people just do not think about this as much as we do.

We understand that, as the saying goes, if you're not paying for something then you are the product.

But less technical people don't consider that, and don't have hoards of technical friends to convince them otherwise. They just think: they using the product, so they're the user, right? We know that's true but it's not the same thing as customer. Most people don't have that distinction in their head.

It's even partially true that Google does want to do things that attracts and retains users, because that's a prerequisite for selling them to advertisers. In my experience, that's an upper bound on the amount of thought most non-technical people would give it.
