I understand the author's point of turning off their ad blocker "to get the non-expert browsing experience" but then they could make a different test with uBlock on for every query and see how it goes.
It's also a bit inconsistent to expect results for downloading videos mentioning yt-dlp while trying to emulate "the non-expert browsing experience"... Yt-dlp is a command-line Python utility. Talk about non-expert! Most people don't know that videos are files that can be downloaded; of those who do, most don't know about the command line or Python.
Yet when searching for "how to download youtube videos" the first result I get on Google is a link to a service called "savefrom.net", which appears to work well and does not seem to be a scam. This would qualify as "very good" in my book.
When searching for "how to download youtube videos from the command line" the first few results are about youtube-dl, including links to github and superuser. Granted they don't mention yt-dlp, but youtube-dl is a good start.
