The problem is that there are thousands of hours of video uploaded to the internet per minute. You can't watch them all, so you have to select what you watch. You need meta-information to select which videos to watch. That meta-information is inherently biased -- after all "which video is important" is an opinion, not a fact.

In other words, you're subjected to the editing process no matter how "raw" your news is. You can reduce it somewhat, but you can't eliminate it.
