The entire article is a PDF embedded into an iFrame, it doesn't render without Javascript enabled. It's very odd to me, I have no idea why they'd choose that format. Maybe the article was written for print and they just decided not to port it? I don't think it would be difficult to show this content in HTML form.

In any case, if you're really curious you can visit the PDF directly, with no JS requirements, at https://harpers.org/wp-content/uploads/2020/08/September_202...
