An idea I've played around with in the past is to have some sort of law that limits how much revenue a company can make from ads. For example, a law that says "A company cannot make more than 10% of its gross revenue from ads or selling customer data".
This kind of law would wreak havoc for certain companies (and content creators). However, just like prediction markets, ads distort and ruin the very thing they are trying to optimize.
