Maybe, but we have all kinds of laws on foreign ownership of media. And for good reason: you don’t want the primary source of input to come from a hostile government. TikTok IS the primary news source for the American youth and is used by half the country. To not intervene is to give away future minds and the country to outside influence.
And for those who say FB is also ruining minds, I don’t disagree, but at least it’s “our problem” which means it’s up to us to solve it as well.
