There's some defending it in general, but it's also just a really tough precedent to allow when it could, so easily, be used to shut down any other service they want by just waving the magic "national security" flag.

It's possible to believe TikTok is bad and that the pathway the US just proved out to banning it in the US has shown that no US court will seriously question the "security reasons" fig leaf. Telegram and Signal are both used by plenty of people the US could easily paint as "security threats" and it's unclear there's any defense to a ban that they could mount at this point.
