<i>But in theory this allows publishers to offer content that is &quot;ad free&quot; because the user is paying for it in the form of data.</i><p>I agree this is an interesting idea, though not necessarily one I would personally choose to use. It might be a short-lived one, though, if the tracking shows that someone who isn&#x27;t willing to view ads immediately also has a low chance of conversion for any later ads targeted based on the data given initially.
