This will never happen because the people who would pay the most to avoid targeted ad tracking are the ones who are the most valuable to advertisers (essentially, people able and willing to spend money). So when you see Facebook making $20 per user or whatever and think “I’d pay $20 to avoid being tracked,” it’s actually Facebook making nothing from a ton of users, a little from a bunch of them, and a huge amount from their “whales,” and the people willing to pay to avoid being tracked are most likely in the “whales.”

I would say with some subscription services you see the inverse of this - i.e. streaming media. IIRC youtube creators make more per view with subscribers than they do with ads, but I could be wrong.
