There are few things that are unbiased, least of all language. Even when communicating a straight fact, the words and tone chosen to communicate it have an inherent bias. One can report with glee or hope or skepticism or anger or just about any other emotion, with positive or negative or neutral words, all of which have an inherent bias. To a person who's happy about something, a reporter's skepticism of that same thing is an unmistakable bias. The point is, that doesn't make it bad. Accuracy of reported facts seems to be a stronger indicator of the "lack of bias" that people prefer.
