The Lumen Database page lists only domain names of the URLs in the complaint unless you solve a captcha and enter an email address. The full complaint lists https://newpipe.net/ itself, while the chrome.google.com (and addons.mozilla.org, and store.microsoft.com...) URLs are to browser extension pages, and the Facebook URL is the URL of a post that has a link to a Youtube downloader.
The list generally seems to be a collection of things that range from the websites of Youtube downloaders and interfaces to simply mentions of them, including a Wikipedia page about Youtube downloaders and a Trustpilot page of reviews about a website for one.
Item 9, meanwhile, appears to be a completely unrelated Soundcloud track that isn't even connected to the complaint description, but appears to have the URL of a Youtube downloader in the title.
