Maybe they think they'll get access to them eventually if they're loyal.
It might seem cowardly, but it isn't that different to what happens every day in business. Society is full of organisations working on the "make the boss' opinions your own" principle.
Then you aren’t a journalist.
The people winning White House credentials are political influencers. Chomsky was an interesting linguist. His political observations are about as scientific as our current crop of Silicon Valley elites’.
The refutation is there are lots of places to sit. Like, yes, the people at a linguistics conference will predominantly be linguists. That doesn’t suggest a linguistics conspiracy.
Chomsky's whole point is that it doesn't take a conspiracy for journalists to share their superiors' views. Not for those superiors to be very aligned with each other.
That's Chomsky's point. In Manufacturing Consent, Chomsky explains how the appearance of collusion can arise without conspiracy. Like-minded people hiring and promoting like-minded people isn't a conspiracy, it only looks like one because people with similar incentives and values will behave in similar ways given similar circumstances.
What he said, and I agree is true and important, is that you won't get to work as a journalist and do things like, say, interview people for BBC, unless you believe most of the things your employer believes.
In fact the most common form of journalism you will find is what's akin to a Propaganda channel of a Sponsoring Party (Defense, Media Company, Political party, Rich Individual with an agenda, etc). Essentialy a PR employee.
But this is true since always.
The kind of journalism we usually think of though is Investigative journalism, but that's a different beast and usually doesn't really pay.
You seem to have presumed your conclusion.
