First of all, the video uploader is promoting a competitor to YouTube. This is not disclaimed clearly.
The video goes over criticism to the CIA, which are fair enough. But it takes some things as axioms, for example, that only the US are interfering/meddling in the world. He presents it as "the US is the bad guy and the world would be fair without the CIA." Which also is a form of propaganda.
It's a bit näive to not see this as anti-government propaganda. The crude reality is: true democracies never existed, and influence between countries is as old as society.
About the "censorship" itself: Youtube's goals is not the same as the authors, why would they promote something that is not what they want to be? They have a huge infant audience, they want to be advertiser-friendly. This is not something hidden or unknown.
They did not delete the video, but they shouldn't promote it. No fault in my eyes.
And at the same time, the buzz around saying "my video is being suppressed" get more views and is even a badge to prove the content "hits where it hurts". Just like rock bands in the 80s/90s would go after being censored or considered 18+ just to sell more.
