I'm not sure why influence should be illegal. What about books and movies? Or even schools and universities? American schools are probably the greatest source of anti-American / anti-Israel sentiment in the country. https://pbs.twimg.com/media/GXm-NYyWEAA1jNs?format=jpg&name=...
If you believe in freedom of speech, you should also accept that people, including foreign people, may try to influence you. China doesn't believe in freedom of speech so they censor foreign sources of influence. Does America really want to go down that path?
Books are quite static.
But dynamic algorithms, targeting exactly you, knowing what mood you have in that moment (by analyzing what you have looked at, liked, disliked), what opinions you have etc. opens up a whole different world of influence possibilities amd I think those possibilities are just starting to get explored with AI. The data is already there.
