One of the problems with claiming that customers are being harmed by the privacy invasion is that the companies can demonstrate that they are only making a few bucks per year per customer on these "privacy invasions", making the most naturally
legally defensible definition of the "damage" being done only a few bucks per year, per customer. The argument at that point that the customer receives far more value than that is very, very easy.
Showing that they do much, much more damage to privacy to make that several bucks is going to be legally challenging, and trying to convince a judge that the damage is yet higher because of my aforementioned nebulous concerns about "the social fabric being censored at the metaphorical-neural level" is going to fail unless you get a particularly activist judge, because they're not supposed to be ruling on the basis of such abstract concepts like that. (That's supposed to be what Congress is making laws based on.)
One of the challenges to my mind here is precisely that on the whole, individual customers aren't being harmed. On the whole, individual customers come out ahead. For most people, this is an acceptable bargain and they are substantially on the winning side of it. It is only once a single entity aggregates substantially the entire market that society and democracy starts to be substantially harmed, even as at every moment, there was never a transition point where individual customers changed to being harmed.
