>If we are so sure that these media are so bad for people, why are so many people still watching it?

Although I don't have an opinion on this particular podcast situation, this statement doesn't hold any water. You are implying that if people do something, it must not be bad for them because.. people continue to do it.

There are tons of things people do that are objectively bad for them. Hard drugs (fentanyl, etc.) being an easy example.
