I don't think the title is a misrepresentation of the article, just the physics:
From the article: "It proves that measurement is everything. At the quantum level, reality does not exist if you are not looking at it..."
The article does appear to be (incorrectly) arguing that this experiment proves one interpretation of QM correct. It's definitely incorrect - some years back myself and others used non-experimentalist interpretations of QM to get the same result - but it's not a misrepresentation of the article.
Yes, the article does quote the physicist saying that. Physicists do say things like that, without adding caveats like "assuming the Copenhagen interpretation, which is the plurality opinion and my de-facto working theory day to day".
But the article didn't include it in the title, and I think that was the right choice. And HN usually tries to keep the original title.
