Note: this is entirely independent from whether TikTok is bad, which I'm more confident than not it is. But contorting our already contorted national security laws around it is not a tenable solution.
It worked for limiting cigarette use and TikTok is at least as bad for you. I think it’s worth a try and the legal precedence is already there.
Frankly, I wouldn't mind if this happens. I just wish we wouldn't swing "national security" around as the cudgel.
What an odd question. The government bans things all the time - can you go and buy unpasteurized milk right now? Or walk into a weapons store and buy brass knuckles? But heaven forbid, we’re abandoning our principles if we ban a data collection platform owned and operated by a genocidal undemocratic government.
It's not even clear what statute you'd use to "ban" TikTok. Is it a national security risk?
I don't see any reason for it not to be in the purview of government.
Every single country on this planet of ours engages in some form of protectionism, whether we like it or not: again, it isn't clear what casuistic justification explains singling out China's protectionism, and even then banning just one company involved in it. Italy doesn't let us sell the sawdust we call "Parmesan," but I'd prefer it if we didn't ban selling the real thing in retaliation.
Finally, for the national risk: what, precisely is the national risk? You can argue (correctly!) that they're a bad actor given this news, and I would be more than happy to see those involved in the surveillance of journalists see the inside of a court. But this doesn't even come close to meeting the standard for a national security risk, weak as that standard has become.
