What's happening here is that the journalist is keying on that phrase used by physicists and repeating it in a popular setting where the reader doesn't know the more precise meaning. It functions as effective clickbait, but the journalist can maintain plausible deniability by quoting the researcher. (Sometimes, the physicists is guilty of doing this purposefully and the journalist is duped.) This is actually a pretty big source of popular-physics clickbait.
The paper(s) revolutionized several fields!
Sorry. It's a lazy dunk. And an unfair one. But when someone tosses it up, I need to slam home the lob.
It's also an important didactic method in pedagogy. You might call it a form of "Student-centered learning", where a significant effort is made to meet the student where they are. Their desires and experiences should guide them to understand the external world through themselves.

I think it can be argued that to say sand dunes communicate with each other is not anthropomorphization at all. I didn't take it that way and I doubt very many people took it to mean that sand dunes were exhibiting sentience and chit-chatting about the weather.
In this situation, the use of the word communicate is accurate to the definition, and also a useful tool for gaining an understanding of what is happening. The word is used because it is useful. It serves a purpose beyond anthropomorphizing for the sake of anthropomorphizing.
But in all seriousness I'm not sure if you're joking or just didn't read the comment I replied to. I don't think there's a time against asking if someone read a comment!
Metaphor is the method by which we have any understanding at all. Anthropomorphism comes naturally and can make complex things easy to understand.
The difference is intent: when we use the term “communicate“, there is an implied intention to convey meaning that simply can’t exist for an inanimate object like a sand dune (as far as we know, anyway).
