I've given it a bit of thought in the past, and my working conclusion is that people don't care about things unless they're sensationalized.

In a world where information is reaching maximum saturation, anyone with internet access has to learn how to separate themselves from the internet to some degree. This learned separation is the enemy of habit, and therefore the mutual enemy of people who make a living off of clicks/views/impressions. To get past that, you need to start using words that pry past our filter of mediocrity and go straight to the brain, or introducing topics that pique our curiosity. No longer is that tacit curiosity enough to make people sit through something, so in comes the buzzwords, exciting rhetoric and loud voices. Internet profiteering is about filing away everything superfluous, and focusing on being the loudest (or at the very least, most listened-to) one in the room.
