The kind of content you describe is exactly the most insidious and effective "propaganda". Obviously, any given piece of content like that is not propaganda and probably wasn't produced for that purpose in the first place.

But what else do you call it when (if) TikTok makes it 5% more likely you see efficient factories and farm workers in China, and 5% more likely you see the tide pod challenge or whatever dumb self destructive behavior in the US? Such a thing is almost impossible to prove or disprove, yet it would be shocking if the CCP wasn't doing this, considering they do exactly this to their own population.
