That message comes from inline Javascript

This page does not require Javascript to read the article and view the images of the author's screenshots

Disable Javascript

or

Add a Content Security Policy HTTP response header that disables inline Javascript

Something like

   http-response add-header Content-Security-Policy "script-src 'none'; img-src 'self'; default-src 'none'"

The later solution is not for everybody but I like it; I am a text-only browser user so I have different tastes in how I prefer a website to look. For example I think a default-src 'none' CSP makes HN look better in a graphical browser. I omit img-src as I just like to read text. If I want to view images I use Ctrl-U view-source: then follow the image URLs
