The magnitude of incorrectness/malicousness in reporting is irrelevant to this: No single source will leave you with a broadly-informed understanding, even if by simple way of time/space constraints in their output.

Even the simplest of biases affects editorial decisions as to which content to prefer over others. Omissions of viewpoints or of counterpoint example stories means you don't get the big picture, even without some massive media scandal. People scream distrust at media channels for leaving out information they view as critical, and go elsewhere to find those details (for better or worse).
