It'll be interesting to see if the Biden admin has the same security concerns as the Trump admin r.e. TikTok. It's still not totally clear to me whether there was ever a real security concerns or if it was just a fig leaf for a political play. Of course, if Biden stops this process, that would not prove that the motivation was political. It could as easily be the case that declining to force the sale is a political move. Unfortunately, with the lack of transparency in the original decision making, it will be hard to ever know which is which.
