If I allow requests to s7.addthis.com, the page loads. Perhaps we can create a shim for https://s7.addthis.com/js/300/addthis_widget.js to at least prevent the site from completely breaking.

Indeed, matching these URLs to an empty script is doing the trick for this page:

      *://s7.addthis.com/js/300/addthis_widget.js
      *://s7.addthis.com/icons/official-addthis-angularjs/current/dist/official-addthis-angularjs.min.js
