While I am reading others’ view points and enjoy it; perhaps just straight to the point to your point first.

Can you tell me what exactly THE ERROR when I want to find a single good thing about TikTok when I don’t understand it?

For your view point, you logic is the following for the good reason using TikTok:

“Addiction is bad, but many people are using it anyway, just like any media back in the days.”

Are you really sure you have answered A GOOD REASON of using TikTok? Sounds like a horrible argument for me. Addiction is a bad habit to begin with, it won’t magically validated just because the media has been changed.
