If TikTok turned out to be State sponsored spyware, would you reconsider?

I support your slippery slope argument. I wonder where your red line is relative to "state sponsored spyware" and "typical advertising ID tracking" or "cool new app from company influenced by an adversarial super power".

All spyware should be illegal. A law to reign in the ubiquitous data collection on everyone's computing devices would be great. Maybe start by requiring all data collection to be opt-in and for a specific purpose. Make it illegal to deny functionality that doesn't strictly require the requested data. "Paying with your privacy" shouldn't be a thing. Crush every data broker.

This law is different to that, it's all about specific actors, not about behavior and actions. A "people we don't like" list. CNN could be on a similar list soon. All constitutional of course - the law will specifically mention how this is all for national security. And no one's speech is being suppressed, the journalists can always write for a different news channel.
