I was referring more to established Media that people consider credible like the NBC, CBS, The Guardian, The New York Times, the Wall Street Journal, The Atlantic, etc. The fact that the only person in "media" who has been severely punished for their lies is a roundly despised figure (without any credibility among established media or the ruling class) is not a ringing endorsement for the system. While the lies of Jones no doubt caused untold hardship for the families of the victims, they pale in comparison to the much more consequential lies told by major media outlets with far greater influence.
When corporate media figures tell lies that are useful to the establishment, they are promoted, not called to account.
In 2018 Luke Harding at the Guardian lied and published a story that "Manafort held secret talks with Assange in Ecuadorian embassy" (headline later amended with "sources say" after the fake story was debunked) in order to bolster the Russiagate narrative. It was proven without a shadow of a doubt that Manafort never went to the Embassy or had any contact at all with Assange (who was under blanket surveillance), at any time. However, to this day this provably fake story remains on The Guardian website, without any sort of editor's note that is it false or that it was all a pack of lies!(1) No retraction was ever issued. Luke Harding remains an esteemed foreign correspondent for The Guardian.
In 2002, Jonah Golberg told numerous lies in a completely false article in The New Yorker that sought to establish a connection between the 9/11 attacks and Saddam Hussein called, "The Great Terror".(2) This article was cited repeatedly during the run up to the war as justification for the subsequent invasion and greatly helped contribute to an environment where a majority of Americans thought that Iraq was linked to Bin Laden and the 9/11 attackers. More than a million people were killed, in no small part because of his lies. And Goldberg? He was promoted to editor-in-chief of The Atlantic, perhaps the most prestigious and influential journal in the country. He remains in this position today.
There are hundreds, if not thousands, of similar examples. The idea suggested in the original OP that corporate/established media is somehow more credible or held to a higher standard than independent media is simply not true. Unfortunately there are a ton of lies, falsehoods and propaganda out there, and it is up to all of us to be necessarily skeptical no matter where we get our information and do our due diligence.
