It should be trivial to work around; for instance, yt-dlp or so (https://github.com/yt-dlp/yt-dlp) and I think you can as-is stream e. g. via mpv or something, probably to the browser too. Some python script for an ad-hoc localhost webserver I'd think.

What is much more worrying is how aggressively Google tries to abuse its de-facto monopoly. I have said it before, I will say it again: Google abusing everyone else is a bad situation. We need to make Google smaller again.
