At least three options to retrieve this without without Javascript or cookies and view in a popular browser. Example script below. Tested with p7zip and Info-Zip unzip. BSD libarchive unzip should work, too.

NB. This cookie banner annoyance does not work in text-only browser such as links. It only works when using popular browsers.

Uncomment one of the OPTIONS. Then, assuming script is "1.sh",

    sh 1.sh > 1.htm
    firefox ./1.htm
