Oh my god here, is the same qualification near the top of the article.
> One of the problems the two friends looked at was a version of a century-old unsolved question in geometry.
On every Quanta article there's always someone welching about some gotcha they think they've found that just demonstrates how trash Quanta's popularizations of mathematical topics is. But whenever I read the article in question it always turns out that the writers and editors over there somehow manage to thread the needle in making their material accessible without being mathematically inaccurate. Vague, yes, but that's why they link to the research in question because it's a pop article not a journal publication.
You edited your comment to add another objection. It is equally insubstantial unless you dug through the paper yourself and demonstrated that the transformation applied could not reasonably be called a rotation.
