The content is not what is being outlawed, only the distribution mechanism. ISIS wouldn't be allowed to own a publishing company in America; nobody thinks that somehow curtails freedom of speech. If somebody so chooses, they could distribute content from ISIS, and restrictions on that would indeed be a restriction on speech. But it wouldn't be a restriction to make it illegal to give money to ISIS.

that's because ISIS is a terrorist organization.

So if you want to make the same argument, you will have to declare china's CCP to be a terrorist organization - and all of the legal implications that entails.

That's not a constitutional requirement. There's no law that says the government can only do this to terrorists. In fact, even if somebody is a terrorist, if they're American, it would still be unconstitutional to deprive their freedom of speech. ByteDance, as a foreign entity, enjoys no such protection.
