I think you are generalizing my claim. My claim is
specifically that the claim that the Chinese is using TikTok as some American programming vector is sinophobic. The CCP could be tracking the location of government officials through tiktok; that is a
legitimate concern. If you want TikTok banned in the US because you believe that they promote dumb content as part of some strategic Chinese plot and you conveniently ignore Meta and Google, I'm going to assume that your reasoning comes from irrational fear of the Chinese. It doesn't make sense to distrust the Chinese when they are doing the same thing as Americans (unless you don't like them just because they are Chinese).
If you want to ban TikTok for another reason (such as their incredibly poor data hygiene, such as tracking every action you do within their app browser), then that is fair and you can reasonably argue that point from the grounds of privacy and national defense.
My reasoning in calling it sinophobia is because if you actually care about "dumb content" the proper solution is REGULATION for ALL the social media companies. Singling out TikTok makes no sense at all.
