I think both of you are mistaken. It has little to do with media consolidation. If the companies which own the media were culturally for the Constitution and the Bill of Rights, there would be little problem.
What happened was Progressivism/Marxism, as an ideology took over the media, starting with the radio networks during the Roosevelt administration when the FCC. Roosevelt put his man in charge. The administration made sure the radio networks were pro-administration, which meant Progressive. Censorship during WWII consolidated the ideological change. The radio networks became the Television Networks. There was a concerted effort to take over newspapers and turn them into Progressive papers. Thus, the Washington Post, the New York Times, the Atlanta Journal-Constitution.
The Associated Press always had a leftist/Progressive bent.
The recent change is because the Progressive media has lost its ability to control the narrative. Now the Media/government complex has to resort to raw censorship to control the information flow.
