Propaganda isn’t always fake news, it can also be true stuff presented in a biased way.
It can also be true stuff presented in an unbiased way. There's a disconnect here between the proper definition of the word, which is perfectly neutral, and its connotations because the what secretary for tsunami safety doesn't call their stuff "propaganda" but "public service announcement". Still the same thing, though, the tsunami safety secretary is trying to persuade the audience to not be stupid and get to high ground as soon as the sea recedes. Very much pushing an agenda, they *gasp* want people to survive and *gasp* use communication to achieve it.
