Two words: Anti Trust. This existing law was made by collectivists as a way to attack capitalism which is why freedom loving Constitutional Conservatives are hesitant to use it. Since these organizations now see fit to use their monopoly status to enforce the collectivist narrative I say give them a taste of their own medicine and bust them up.
DUH!
I agree with this part of your statement absolutely. The existing media is a monolithic group dedicated to helping their political allies get elected.
The media manipulates elections with their biased coverage, and as an ideological monopoly under one party control, they need to be broken up.
