People of Lemmy, what do you think would happen if POTUS Donald Trump decided to cut all US digital services to Europeans?

Looking at this Mastodon post (in French) where Europeans explore what would happen if Trump blocked all American services in Europe, I thought it would be a great question to ask the people of Lemmy. So: what do you think would happen if POTUS Donald Trump decided to block all U.S. services to Europeans?
