I don't understand why people are so enamored of personalized ads. Advertising was around a long time before personalized ads were even a thing, yet it managed to still work by targeting publications that matched the target customer. This was accomplished by geographic location, for general consumer ads, or by interest, for targeted ads, B2B, etc.
It's about value. Ads were cheap back then because you couldn't be sure the people seeing them cared. Now that you can be reasonably sure you can charge more for the experience.
