You are missing the forest for one very odd tree. Yes, the tree is wacky, but
* Every private media company has beneficial owners
* Those beneficial owners are rich
* Rich people who own things for a living have incentives opposed to those of most people, who work for a living
These are not conspiracies, they are just basic facts of capitalism.
That there are a select few who own the capital, and that those people generally do not overlap with the people who work, is more or less the original definition of capitalism. And I don't think its controversial or a caricature to imply that those two groups will have different incentives.
From Wikipedia [0]:
`The initial use of the term "capitalism" in its modern sense is attributed to Louis Blanc in 1850 ("What I call 'capitalism' that is to say the appropriation of capital by some to the exclusion of others") and Pierre-Joseph Proudhon in 1861 ("Economic and social regime in which capital, the source of income, does not generally belong to those who make it work through their labor")`
