Early on in high school we had one of the sports coaches substitute for a science teacher for a few months. The sub gave us a bad formula, and I spent a while on getting her to correct it. She pushed back, so I even wrote a very small paper showing how the formula she gave us didn't make sense because the value would have to have certain upper bounds, the formula would have to have a certain "shape" to it, etc. It was somewhat rewarding to care about the concept enough to do this, but it made the sub cry, and several of my classmates were angry and annoyed at me. I think this article, even if it was true, downplays the social penalty that the kids who speak up might pay.
