@KimSJ @dotjayne good point. If cross-context behavioral/surveillance/personalized advertising was really a good way to match buyers and sellers in a market, then by now it would been possible to show that people with privacy tools and/or settings are buying worse products and services ( https://blog.zgp.org/easy-experiment-behavioral-advertising/ ) But it looks like the effect goes in the opposite direction.

Instead of assuming a trade-off between market and privacy goals, better to see a win-win situation when it presents itself
