The article is about the subject's social justice activism, not about her physics research. Nothing wrong with that but not what I was expecting.
While you say it's not physics, to me it is because fixing one problem will help the field so (again, to me) separating them seems a mistake.
But that's just one POV.
You may reject the label 'physicist', I'd understand that, but results are results. (Edit: in which case, does the label matter?)
