So, starting now, Google started mandating full JS for YT, effectively breaking all third-party clients and locking the site to their official client.
This reeks of DRM.
UPDATE: Installing Deno and installing yt-dlp through PyPi fixes yt-dlp but the very idea that Google is mandating JS to lock down YT in an attempt at pseudo-DRM is still crappy.
UPDATE #2: inv.nadeko.net is working again for now.
Yep, yt-dlp has already been fixed. Those devs are really awesome.
I mean, if you can display it on your screen, there must be a way to also save it.
