While I think this case is silly (bad), First Amendment protections are only available for U.S. citizens and to a lesser extent to permanent residents (we've seen that permanent residents can have their permanent residency canceled). EDIT: To be clear foreigners can't be imprisoned in the U.S. for their speech any more than a citizen, but unlike a citizen they can be removed from the U.S. because of their speech.
Also, this is an action by CBP, not by the POTUS. I seriously doubt there was any order by POTUS regarding the speech of foreigners abroad. Most likely this is just a zealous CBP agent making this decision. I've been given the third degree by immigration officers in the U.S. and Canada, and it always felt very random.
