(1) He does imply that in the script yes, in several ways. Pay close attention to moments like "like a good democracy should never have interference".

(2) The bit about YouTube hiding is good point taken, I didn't notice that, I thought it was just not showing up in recommended videos.

(3) He is also trying to create a buzz, the homeland security visit is not related to that video. My point is not that it is not worrisome, but that this is nothing new. The US is like this since the beginning. Have you ever seen what happens to journalists that crack open the NSA and CIA?

(4) And it does not imply that, but implies that YouTube is not a platform for free speech, as it has never been. No novelty here. Surprisingly if it was the TV times this wouldn't even go live, no it is going live. The system is changing little by little, but doesn't mean it is 100% free speech. Never was.
