Well, YouTube policies are now barriers in order to find out the reality. Infowars has a particular reason of posting those videos and YouTube should reflect a sense of discovering based on an unbiased analysis.
Remember, there are other new feature that are competing YouTube such as Dtube, Facebook videos and other more. Should we say that YouTube is loosing it's reliability? Yes, because they do not allow the people to trace the original of the problem and the actors involved.
If CNN can flag Infowars it's fine, since infowars can also flag CNN, but if YouTube flags Infowars, then we may no more hear from them. At the end of the day, only few people will have to enjoy YouTube cause it's no more portraying the freedom of speech.
This is a country and it should be opened. The people must search deep doing causes and origins of the unpleasant activities that are happening in the country, if not we may experience the worse in the near future
