How would a network ban be enforced? TikTok doesn't even communicate directly with Chinese servers - I block connections to China on my home network, and my kids can still use TikTok on the wifi, so I'm confident there are US servers.

I even more doubt that we have the infrastructure in place to do a network-level ban (whatever that would mean) for a single app. It is much easier for me to believe Google/Apple could be strong-armed or sweet-toothed into delisting the app, if it really came down to it.
