It seems like a bad science yes, or perhaps editorialized by media. And completely unexpected that all information proliferation follow power laws. If they were comparing different categories of information (political, rage bait, technical discussions, neutral boring news) etc they could say something interesting. But this is such a narrow focus on a mostly value judgment based class of misinformation. It would be much more interesting to know how certain types of information differ from each other in terms of topological properties.
