I'd like to respond to that.
In fact the CBC's sponsored study found that the CBC was a toady to the Liberal government. I'll read to you, if I may, a quote from the study: “According to the quantitative opinion data, CBC News not being perceived by as many English Canadians to be 'politically biased' or always reflecting current government opinion of events”—and at the time of the study it was a Liberal government—“ would further enhance these core values.” In other words, he's saying the CBC would do better than to parrot the Liberal viewpoint.
I think this flies in the face of your point.
