Public domain is special. You free yourself of all ownership which means that somebody else can pick it up and relicense their distribution of it, including saying you cannot do things with it. I emphasise "saying" because that's pretty much all you can do unless they know they're the only entity distributing it.
The problem here was trying to enforce on something that was obviously non-exclusive. This mistake happens with all sorts of content available through multiple channels. Getty should have marked it as such on ingestion.
