I think people in China would be able to use Starlink without the great firewall being in the way. Just having access not be routed through ground based, hardwired facilities will go a long way toward preventing this type of thing.
There's no reason to ban TikTok or other apps if people in China have unrestricted access to US companies.
> Do you think Starlink would be allowed to route TikTok traffic if it got banned?
Yes, without a doubt it would be allowed. The "TikTok ban" has already been signed by Trump, and nothing in the order prohibits AT&T, Verizon, Comcast or any other ISP from routing the traffic.
The executive branch doesn't have authority to prohibit legal speech. It has some powers to regulate commerce, that's it.
