I'm not a cybersecurity expert, but I think TikTok is a great illustration of the kind of complexity around technology, supply chain and data management, and we have to take a look at it. This is similar to the situation about the global supply chain for personal protective equipment. I think what is revealing is that the infrastructure behind some of these technologies like TikTok is not as simple as some would make it out to be. It's not as if they are listening to every TikTok.
The security of the data, where it is stored and how it is used, is definitely a national security concern, because, again, if they are able to use the data to prosecute under something like the national security law, then that becomes a direct threat that I think people may not recognize, which exists right now.
