It actually isn't. Campea does some, but if you look at the titles of videos by Screen Junkies, Collider, Schmoes Know etc they're pretty straightforward. What they say is going to be in the video is what is in the video, and Collider/Screen Junkies do source information.
Besides, every form of media does click bait. Do you think the news boys hawking the New York Times were yelling about the story on road repairs on page 18? No, they were talking about the mob hit, political scandal or celebrity marriage that was on the front page, above the fold in bold type.
