US Citizens still have the same freedom of speech and freedom of thought and democracy. Those rights don't extend to foreign adversaries. If you want to relay Chinese or Russian or Ukrainian or Israeli or Hamas propaganda, you are completely free to do it, without censorship. Limiting the ability of any of those countries to project it within the US is reasonable stance.
You're limiting the information US Citizens can get from the outside world - therefore you are limiting their freedom of thought and access to information.
I think it's a dangerous road to go down, the US is already extremely inwards facing and suffers from not knowing much about the outside world. I've had hundreds of US Citizens talk to me face to face who don't know what language we speak in Australia, don't know we use different money, not know the seasons are backwards, not know it's a 15 hour flight, not know we don't have a president, etc. etc. (this list is endless). US Citizens are not very well educated about how things work in other countries, clearly to their own detriment.
Just yesterday I was talking to a friend in the US saying my friend has 18 months fully paid maternity leave and he almost fell over. His wife got 10 weeks.
Many countries do things better than the US, and it's dangerous to limit US Citizens learning about that, else they will have no notion things can be (and are) better elsewhere, and should be improved.
