It's not a technical explanation, it is a socio-national explanation.
Yes, Google, Youtube, Twitter, and Facebook are indeed spyware. However, they are US-based, and US-centric. While some information can leak to the Chinese, data access (to them) is not the primary purpose of the platform.
Unlike TikTok.
If Google (who has shown a friendly hand to Chinese) started providing them any sort of access to the data, I'd campaign for their shutdown as well.
OK, fair enough, and I respect your answer.
But I am more fearful and opposed to the tyrant Communists a few miles down the road (Marxist BLM and Antifa, the current democrat party, the DNCMedia, Hollywierd) than the Chinese Communists 4000 mile away.
We will go to war with China if they attack us (and Trump is president). Meanwhile, all I see of the Left these past few months is violent attack after attack and no one in the USA—except maybe Donald Trump, with no support—lifts a finger to stop them.
The technical aspect I’ve heard about Tik Tok that differs from the rest is they are using facial recognition to make filters for people’s faces on the videos... And then saving this information in their databases. That’s a huge invasion of privacy, but I don’t really see how cataloging US teenagers faces is useful to China in any international struggle.
