As for it getting banned, TikTok was banned partly because of credible accounts of it having been used by China to track political enemies. Are we thinking they'll expand the argument on national security to say that any application that transfers data to China is a national security threat? Because that could be a very slippery slope.
And in any case, such a measure seems like it would only bar access to the DeepSeek app. Surely no one could argue that the underlying open source model, if run locally on American soil, could constitute a security threat, right?
