See, the way it works is "our alogrithm sees that you follow Susanna, Dana, and Sela....how about you check out these OTHER attractive middle-aged brunettes?" And I say "well....this does match up with my interests...."
I can go one better than that. Got a new Packard Bell setup in the very early 90s, to start law school. As I was setting it up, it came with various software giveaways and promos, including one on the relatively new media of CD-Rom. It was Prodigy. I opened it up, and read all the material with it. And I distinctly recall the moment that I tossed it into the wastebasket next to my desk, saying out loud to myself "'Internet?' Sounds like a scam." I was either way wrong....or way right.
Oh, and Tik-Tok is absolute hot garbage. It disseminates information pursuant to an algorithm that is intended to undermine the social and political order of every country other than China.
Imagine it was 1942, and there was a massive media empire in the US that was openly owned by the German National Socialists, disseminating information that was openly intended to undermine support for the US and lead to support for the Nazis. When nation-states play around in such endeavors, shit happens. If China doesn't want Tik-Tok banned, it should have let it be an independent enterprise, with no government interference or direction. It hasn't done so. There is a very good reason it hasn't done so -- because that would ignore and be contrary to the very purpose of Tik-Tok.
