It isn't really whack-a-mole though, because despite the media coverage there is no "TikTok ban bill." Instead it's a "Hostile nation can't own majority stakes in media companies in the US" bill, and this SCOTUS ruling sets the precedent that can be enforced on as many entities as required.
On a more amusing note the Chinese did NOT expect a bunch of Americans to show up on RedNote, and they're not thrilled so far. It seems that sharing details of how to organize labor unions, protest against your government, 3D print weapons, and so on wasn't what they were hoping for either. There's allegedly talk of them siloing off the new joins from abroad.
So how big does Rednote need to be to "majority stakes in media companies in the US"? I don't like this ruling at all, but it feels very American to see another looming threat and say "well, I'll just wait until it gets too big to deal with it".
