>I guess if many people block sponsor content, this kind of vids will die.

Then so be it. I miss when people uploaded videos for the sake of it, not to make money by way of exploiting the users' cognitive vulnerabilities. I remember the days when I could search for a video on how to replace my dirt bike's carburetor and it was less than two minutes, didn't include any ads, and was straight to the point, all first person POV; you wouldn't even see the guy's face. Nobody was trying to get rich off it. It was all about sharing it with other people.
