As I said, there is no such thing as totally unbiased reporting, some or just better than others. The news media does not report truth. It reports what is believed to be the most important stories and what is being said by leaders in government, businesses, and other major organization. They can not and should not try to determine who speaks the truth. They can not and should not try to air the dissenting voices. There are other organization that will do that such as Fox News, MSNBC, talk radio, podcasts, magazines, and websites that will analyze the news, report all those dissenting voices, and telling you what is true and what you should believe.
In regard to Covid, the media did as they have always done, report what the leaders in government, industry and other major organization were saying. You can't except them to determine what is true and false about Covid when the CDC and many research organization couldn't.
Early in the epidemic, the CDC said much of what we believe today will change as we get more data. An in fact, many times it did change.
