Also, fairly reputable sources that produce mostly good quality journalism will slip in misinformation or hit pieces at the behest of political and corporate entities.
Examples are the New York Times writing a hit piece against Tesla, where it turned out they had driven the car in circles in a parking lot for hours to get the battery to run out, but didn't think that Tesla might be able to get data on what they did. Turns out the author of the article works for the oil industry. The NYT also regularly publishes as fact things told to them by the Pentagon and three letter agencies, rather than calling the information alleged.
