I must admit that I didn’t read the linked article.
I just want to add, that there are fakes, that take a file (e.g. a photo) and use it in a different context together with a factual lie.
A fictive example: An article about people from political group X demonstrated in the streets against upcoming law Y. A backward image search on the web would reveal, that the demonstrating people on the photo in the article were instead demonstrating against something else in another country. So sometimes provenance can do good like uncover fakes.
