Written by somebody who hasn't taken 1 look at yt-dlp source code or issues. Google regularly pushes updates that "coincidentally" break downloaders. The obfuscation and things they do to e.g. break a download by introducing some breaking code or dynamic calculation required only part way through the video is not normal. They are not serving a bunch of video files or chunks, you need a "client" that handles all these things to download a video. At this point, if you assert that Google doesn't want to secretly stop it, you are either extremely naive, ignorant, or a Google employee.
