I'm a parent of two, and step-parent to two, between the ages 5 -11. I think a lot about this, and one of the biggest issues I see (besides the many valid points I feel the article raised) is that with the rise of Internet video, we are showing kids to kids more often, if that makes sense.

I grew up in the 80's, and cartoons were most of the media I consumed. You usually saw anthropomorphical characters depicting behaviors. When you did see live action, it was usually centered more around adults teaching or mentoring the kids (or Muppets), and when kids did appear, they were polite unless being used to illustrate bad behavior.

Today, with so much self-published content, kids are seeing other kids, often acting in outrageous ways to get views, likes, followers, and fans. When media became decentralized, I think we lost a powerful cultural platform for shared experience and norms, and it is starting to show.
