Videos like this are only accessible in some countries if you provide YouTube with a government ID. In my country YouTube blocks a number of videos from public broadcasters this way.
It used to be that youtube-dl worked, but on that CIA video I now get:
[youtube] _2khAmMTAjI: Downloading webpage

WARNING: unable to download video info webpage: HTTP Error 410: Gone

Meh.
The following content has been identified by the YouTube community as inappropriate or offensive to some audiences.
Was it really "the community" though?
Anyway, that video doesn't seem very out there at all to me. That the CIA has committed various things most reasonable people would classify as "crimes" and "terrorism" seems like common knowledge to me.
Have you tried the YTBypass, 'youtubensfw' redirect? At first, the video won't load, but there is a notice to 'click this if the site won't load.' which brings up the video. It becomes possible to download the video then, although it is very slow.
There’s no major conspiracy here other than YouTube becoming increasingly hostile to the open web.
I would put money on Rumble becoming a major force in social media over the next ten years. It feels more like early YouTube than YouTube itself has felt for a long time.
