I think the issue is that TiKtok is just as bad as all the other social media and they are owned by a foreign adversary.
Foreign adversaries (ie China, Russia and America) use social media for influence campaigns on each other and therefore their social media platforms can't be trusted. This is why Chinese people similarly can't use Google or Facebook
Maybe I should say I'm not in the US. Media literacy isn't brand new to me. But the CFR was completely foreign (pun intended), there isn't quite anything like it where I live.
Although the propaganda model of Herman and Chromsky quoted in your link is very much a mirror of our media too. (Most notably in our television network, own by a single group)
If I understood properly that was the point of your sarcastic comment on the CFR right?
