I wanted to keep a copy, but the download button basically doesn't work.
Instead of downloading, it opens in a new tab.
Chrome provides 0 options to download or save the page. There is no print option, and 'share' saves the page url as a text file.
Firefox provides a print option, but it saves as a pdf that's so horribly compressed that the text is like 3 pixels tall and entirely unreadable.
DuckDuckGo provides a print option in full resolution, but it cuts off everything to the right of the letter 's' in 'usenet tree', saving only a narrow slice of the page.
