Propaganda is a very well known way to enact influence on a foreign nation.

Historically, the most effective use of propaganda is by the domestic government on its own citizenry. Closing out foreign sources of media, shutting down opposition venues for news and discussion, and criminalizing private parties that attempt to distribute outside opinion tend to facilitate the imposition of a national propaganda campaign.

The people making the content have the right freedom of speech, but the people making the editorial decisions on what is / isn’t shown do not have that same right if they are not American citizens.

This isn't simply closing off access to "free speech", it is closing off access to reporting on world events and international opinion. American citizens do not have the right to free expression of they are blinded and deafened to any kind of outside perspective.

How, exactly, do domestic residents gain information from the outside world if the state has the right to censor anyone outside of its borders from sending news into the country?

The primary concern isn’t the content, it’s who controls the editor’s desk.

If the US policy towards international media is "only American citizens have the right to sit at the editor's desk" then we're not talking about free speech, we're talking about political control of the press. The "American citizens" canard is simply an excuse to deny Americans access to outside media.

It is also highly disingenuous. Nobody is proposing the US block access to the BBC or CBC on these grounds.
