Full text 1A:

Congress shall make no law respecting an establishment of religion, or prohibiting the free exercise thereof; or abridging the freedom of speech, or of the press; or the right of the people peaceably to assemble, and to petition the Government for a redress of grievances.

There's nothing in there about foreign entities or any other authors of speech. It's about speech (and religion and assembly and petition) itself, which the state is directed to leave the fuck alone. The variety of zany things any particular entity might want to say is not even the main point. Freedom of speech is important because it means we get to hear and read and experience speech from everyone and everywhere. As soon as a line is drawn around speakers we're not allowed to hear, we no longer have the freedom of speech. Many people are confused about this because they habitually speak without listening. Those of us who mostly listen are not confused in this manner.
