I have noticed that YouTube no longer requires the "rolling cipher" for unthrottled downloads. Also, it appears this court was not made aware that users can still perform throttled downloads without using the "rolling cipher" and without "youtube-dl". The download links are in the YouTube page source, as is the case for hundreds of other video sharing sites across the web. If YouTube really wanted to stop users from downloading it could easily do so, by removing those links from the page, for starters.
