This is awful. Autistic kids don't need to change how they view emotions. Other people need to be more accepting that other people may not care about their emotions as much as they do.
I agree with you that the real thing here is that we should accept all people regardless of how they view/prioritize our emotions and meet each other where we all are. But until we are all in that same agreement, I'm all for tools that provide increased agency/information to people who want to use those tools.
