You and others unfortunately misunderstand the purpose of a publicly funded broadcaster. Taxpayers support the CBC so that at least one major electronic media is not held captive to ratings. Despite their protests to the contrary, there is an inherent bias in all private media for the very reason that profits and commercial interests take precedent over independence, truth and relevance. 

Why fund the CBC if all it can do is mimic its private competitors? Which is pretty much what it has done (and then not all that well) for the past 20 years or more. The fact a succession of prime ministers including and particularly Harper drastically cut the CBC's budget helps explain but does nothing to justify its failing performance. 

When CBC replaces Mansbridge, maybe it could forego the American MSM nice voice/pretty face standard in favour of someone who can not only read the teleprompter while appearing trustworthy, but who actually understands history, facts and dynamics behind the news.
