Why haven't advertisers noticed this is why we install blockers? Deep-tracking, ultra-personalisation ending in creepy ads were bad enough. But the flip-side is if there's only one industry interested in your activities, you only see those ads, whatever you're looking at. Lets go back to the 2000s, where ads targeted content, not users. Before you start fretting about CTRs, you can't click what you don't see. That's the hole advertisers need to dig themselves out of. And even before ad-blockers ruled supreme, targeted advertising was sold to publishers as a way of increasing CPM. Truth is payouts have been in free-fall since online advertising began.
