What's interesting, does that strategy end like: less effective ads -> need more of them -> raise ad price + show more of them? Another thing is regarding k-anonymity which I suppose privacy-first guys would use. If I gather user info with a high entropy, I don't have an incentive to sell it to anybody and create a competitor, and it'd probably illegal to do that. But if I anonymize the data set into a k-anon data it's now less restrictive to sell from legal point, also I'll probably sell that data to third parties just to make ends meet.
