To me, this whole thing just comes across as craven and excessively politically motivated by the US government. If they were really concerned with apps (whether or not they're owned by the Chinese government) collecting and selling user data, they would pass adequate and enforceable privacy laws. Banning one specific app is addressing a symptom rather than a root cause, and any solution to an issue like this ought to apply to the entire field more broadly. I don't necessarily think that banning TikTok is a bad thing, but to do so in such an obviously politically motivated way belies a lack of concern about the underlying issue (i.e. the mass harvesting of user data).
