Not only Youtube, but Facebook and Twitter and others are censoring videos and more. But, it is understandable that they would do this. There is a fine liability line between between them and those who do the posting.
Suppose a user intentionally posts a dangerous or harmful video to Youtube. Then, some third party is harmed by the contents of the video. Who is really liable, Youtube or the original joker who posted the video? Maybe both or maybe neither.
Youtube looks at the cost of potential law suits. A lawsuit against Youtube by a single person might be a little costly to them. But a lawsuit, or series of them, by governments or big companies, could be expensive to fight. And if they lost, who knows what would happen. Maybe it has already happened.
What we need is a form of media that is totally decentralized, so that the media itself can never be sued. Such would throw the damage claims into the lap of the individual posters of the content/video... if he could even be identified.
The media programming would have to be good enough that it could compete with Youtube in speed and organization. Does anybody have any way to make something like Youtube that is completely decentralized?
