I mean, that's the definition of PR. It's their job. And the longer you think that your opinion is your own, the better it works. Confidence tricks work the same way. But I'm not just defying you, you also have a point. PR can't make people like
anything. The target audience is already in some state, they came from somewhere, want something, already have some preferences, can be described to being on some trends. What effective PR can do is take what they have, and align it to these states, trends, preferences. Like how it's said in the movies, hypnotics can't make you do something you don't want to do, or something that makes no sense to you. The "seeds" have to already be there for it to work. Now I'm not sure about hypnosis, but PR, propaganda, advertisement works this way.
And this is in no way exclusive to Disney, or PR. It's natural to want others to do something for you. PR is just the current legal way to describe this effort.
