@lightweight Unfortunately both of those links lead to proprietary JavaScript.

Even if the JavaScript is under a free software license, in the context of the world wide web of arbitrary remote execution, the user doesn't have a reasonable ability to exercise software freedom;
- They can't reasonably check what they are running before running it.
- They can't reasonably choose to run only part of the software.
- They can't reasonably choose to run an older version if they don't like a newer version.
- They can't reasonably change the software.
- They can't reasonably share any changes to others and reasonably expect the other party to be able to run it.

Only the host of the website gets freedom.

Unfortunately it seems that all remaining public invidious instances serve malware to the user (like a cryptominer, but instead of using CPU cycles to mine cryptocurrency, it uses CPU cycles just to waste them - good luck to those without the latest CPUs).

Thankfully; `yt-dlp https://www.youtube.com/watch?v=zXHq04W0kBs` works.
