That's a terrible value proposition, especially for someone who finds that CBC is extremely politically slanted in their news coverage. I would say I find regular CBC consumers slightly less informed on average if anything.
The stories are different too, which might come from an incentive to provide a public service rather than a sensationalization of what is happen as a profit motive.
Realistically, the CBC's left leaning is a balance to all the conservative leaning of the other broadcasters.
There is value in providing content that isn't 100% profit incentivized, especially as a predominately left leaning country (relative to the USA).
