This whole things looks more and more embarrassing. From the outside it just looks like the US is struggling to compete and so they create extrajudicial barriers based on "secret evidence" to block competitors. The hypocrisy is that this is the exact anti-competitive behavior the US has been criticizing China for years. It's possible these companies are doing nefarious things. In which case create a country-agnostic…
I feel like I don't really have any moral problem with US passing laws to protect US interests, as long as the laws aren't super unreasonable or evil. They're, like, unfair to some people, but not.. really... morally wrong? The moral complaint about China isn't that they have anti-competitive laws, it's the Orwellian thought-suppression psy-ops stuff.
I mean that's like a "bigger" issue. I think it's a completely fair to decide you should just not conduct business with companies under authoritarian regimes (see N.Korea Iran Myanmar etc.). If you wanna blacklist the whole country then okay.. but here it's some indefensible middle ground where you continue to do business with them, until it's inconvenient and some bureaucrat decided it's making you look bad so lets just ban some of their strongest companies to cripple them. We will do business with you as long as you only make low end widgets thankyouverymuch.
That might not be what's actually happening, but that's how it looks
