Dumb bullshit.
If that's where voters are, that's where a campaigner should go. And it's not an immediate ban, it's a requirement to sell that part of ByteDance to a not-Chinese company, or else it will be banned. Americans are free to use it in the meantime, and probably even afterwards if they feel like jumping through hoops to make it work, as no penalty is applied to any users.
Not that I expect a propagandist to give a shit about the details.
