Anthropologically, there are a few different schools of thought. You can talk to ten different people and get ten different theories on it.
And I absolutely agree. With sapience, comes the capacity for wonderful things. But at the same time, there exists the capacity for great evil. My point was that restricting the free flow of information isn't a solution. Humanity is a simultaneously beautiful and ugly thing. And the vast majority of us aren't lunatics that wanna blow our neighbors to bits or pump them full of lead. But the few lunatics that do wanna watch the world burn? YouTube can't stop them. You can't have an intellectual elite that lives in the light with the mission of keeping the masses in the dark. We've been there. That's feudalism. That's slavery. Information itself is neither good or evil: it's what someone does with it that's important.
Having said my piece, Google has every right to censor videos it doesn't want there. They own the servers, they control the content. If their customers don't like the way they do business, perhaps they should consider Bing.
