Unfortunately, the site in question requires JS; without JS, it displays nothing but a blank page with a spinner. It doesn't even have a <noscript> element.
Ah, I forgot I already have c2.com setup. Trust c2.com, Block the hypothes.is entry. That's the beauty of NoScript, you finetune things once and a while and the web goes much more smoothly. Since I visit mostly the same sites every day - it's not a huge issue. And for sites I haven't visited - I already block many scripts I don't like globally!
