I don't think anyone's arguing that it's not legitimate for a country to ban a company on national security grounds, but that this is stretching the definition of what constitutes a national security threat.

Which companies currently banned in the US would you say are comparable to TikTok in terms of the threat they could potentially pose?

I would say that mass surveillance by a foreign country is not a stretch.
