However, if I was to criticize anything about their journalistic integrity, it's the tendency for their reporters to inject too much personal opinion. Though they do often succeed at concluding their pieces in a way that leaves the consumer considering multiple perspectives.
We don't have nearly enough (imperfect or not) media companies pursuing the types of stories Vice does. Given their willingness to publish exceptionable stories, it's no wonder there are significant attempts to discredit them.
