The way you would solve both issues is simply have data protection laws that affect all social media companies, rather than singling/discriminating against one company because it's "foreign", and moreover "Chinese".
That's also a copout that liberals spent a few years repeating in Spanish for some reason. TikTok is not at all a problem. The fact that all of your data is already on sale, cheaply, publicly, and legally, is.
You say it's a copout and then you don't explain why. I can believe US data through TikTok is at risk due to CCP origins and I can believe our data is on sale in general. I can also believe that both are an issue.
