I understand they want clicks and the general incentives for clickbait, and thus why the title might be a tease. But they also need to keep people on the site to view and click on the ads (especially near the bottom). So, for instance, why not tease more with a subtitle? Maybe the idea is that, empirically, the small fraction of people who will trudge through the article to find the mystery topic, for whatever reason, nevertheless stay for long enough that total ad exposure is higher. So the bounce rate is high but outweighed by these outliers. It still doesn't help me understand their motivation though. Like, there are a thousand news articles each day that begin with an intro thats indistinguishable (information-wise) from this one. Why read this one?
