Blocking via pocket inspection. You can block the traffic on your own network, that's how Purdue does it.Never used Tiktok, don't have any social media accounts outside forums.
How could you ban it without some sort of national firewall? I guess you could prohibit US companies from advertising on it, but I don't understand the logistics of banning it all together. I think it's a pretty dangerous idea to ban it and not sure how it would pass 1st amendment court challenges.
Apparently there's a plan to have Oracle hold all the data in a facility in Texas and any data released to outside entities would require approval from the US gov't. That seems a pretty reasonable accomodation vs a feckless ban, but I fully admit I may be missing a lot of techno-wizardly that makes that plan unreasonable as well.
On a national scale? The US isn't as good as that as the Chinese, but it can be done.
