Is this bad manipulation or am I just being too negative?

I just attended a Zoom “course” by a random woman on FB who claimed to be a famous entrepreneur coach. The course was fine, there were a lot of problems that prevented it from being good. But one thing that stood out for me was when she talked about how to market your online courses to parents. She told people to reach out to parents personally and ask them if how their kids were doing. She assured that 90% of parents would say something like “My kid plays mobile games too much!” And that would be a great opportunity for you to tell them about your classroom. She also told people to tell parents things like “John is an intelligent child, but he forgets things easily, so you should get them to online class as soon as possible or else he will forget his lessons!” Another advice she gave people was that they should tell parents to watch out for their kids and make sure they went to class as much as possible, because no one wanted their kids to play all day.

To be honest, I find that really manipulative. You would manage to get the parents to pay for your class, but that doesn’t guarantee the kids to be happy with it, because they are going to class under the pressure of their parents. Moreover, the advice also preys on parents’ insecurity about their kids doing worse than other kids, and nothing good has ever come from kids being compared to other kids. I know the goal was to market your classroom, but the advice just sounded… petty to me.

What do you think about the advice?
