Because the kind of people who run CNN and other staples of traditional media are the same people who covered for people like Jimmy Savile.
Mark Thompson is Chairman and CEO of CNN. Here's some blurbs from his Wikipedia, the Savile one being the most salacious.
In September 2010, Thompson acknowledged some of the BBC's previous political bias, which he said he had witnessed early in his career. He stated: "In the BBC I joined 30 years ago there was, in much of current affairs, in terms of people's personal politics, which were quite vocal, a massive bias to the left". He added: "the organisation did struggle then with impartiality".
Fucking news to me, mate.
Although Thompson departed the BBC before public exposure of the Jimmy Savile sexual abuse scandal and is not noted in the BBC chronology of the unfolding coverage, Thompson faced questions about his role in the events around Savile's actions and BBC coverage of them. According to a New York Times review, Thompson denied knowing of a BBC Newsnight programme on accusations against Savile before it was dropped soon after Savile's death in October 2011.
Literally everyone around Savile is fucking trash.
In a 4 February 2024 investigation by The Guardian, some CNN staff blamed their channel's newly appointed director Mark Thompson for what they described as biased reporting of the Israel–Hamas war. The staff criticized their network's coverage of the war, charging that it had promoted Israeli propaganda, and gave more attention to Israeli suffering, and the Israeli narrative of the war. One staffer claimed that this bias was systematic and institutionalized, as many journalists' stories were forced to be cleared by channel's Jerusalem bureau before publication. Staffers claimed that statements by Hamas and the Palestinian Authority were rarely reported on, while Israeli statements were taken at face value. A CNN spokesperson denied the charges of bias.
That's to say nothing about the pro-Trump head of Discovery (which owns CNN) David Zaslav slobbing this guys knob.
Discovery CEO David Zaslav shared, "I am confident he is exactly the leader we need to take the helm of CNN at this pivotal time."
Thompson was also formerly at the New York Times, another publication that has been swinging to the right. However, if you check out the Lifestyle section of the NYT, you quickly realize why, because it's aimed at rich fucks with a second house in the Hamptons.
It's literally in their short-term-financial-interest to get Trump. They don't give a damn about long-term-interests at all.
