> Google users are not (in most cases) their customers but a product Google sells to their actual customers.
No, Google users are suppliers of a product (ad views) that Google sells to their customers. But they are suppliers that are paid via in-kind exchange (with Google services) rather than cash, which is exactly equivalent to being customers of Google services that pay with in-kind exchange rather than cash. So, in a very real sense, those users are customers.
Do Google users get slaughtered? I mean, that is why it's undesirable to be a chicken in a chicken farm, right? If it weren't for that, then choosing the farm you are on would be quite the desirable ability.
What if all that happened on chicken farms was one of their feathers got plucked once in awhile?
