You can go further back from Chomsky. I'm currently reading Guy de Maupassant's Bel Ami, which gives a grim portrait of journalists in 19th France as lazily serving the interests of those in power[1].
The thing about the situation is historically journalists have always served interests and ideologies. American journalism has a long and storied history but the idea of purely objective journalism is itself a particular kind of rhetoric and particular kind of spin that was a fine product of early 20th America. In reality, 90% of journalism is "spin" and 90% of journalism has always been spin - or interpretation or perspective or context or whatever spin you want to give spin. That journalist serve their sources, their ideologies, the interests of the owners of the journal and so-forth isn't bad unless you think everyone with power is evil (which is plausible but if you believe this, then you would be supporting some ideology outside the mainstream, which also has it's spin).
It's fairly well documented that Julian Assange worked quite actively to make the release of the Clinton emails serve Donald Trump (coordinating with the Trump and other no-nos) - not even that there was lying involved but here he went from citizen journalist to propagandist. But I don't think becoming a propagandist makes someone worse than the cause they serve. In the case of Trump, I happen think made that made him viciously evil but that's happenstance relative to the question of journalism.
Forget about the current election. Suppose you had your ideal candidate running against a definite evil, someone who pursue policies that would hurt or kill your friends and family, in a close race. If some piece of pure dirt, a politically contentless but deeply embarrassing true fact about this honestly good candidate surfaced, would consider those who pushed this fact relentlessly to be paragons of virtue?
There are some articles, a few, where pure truth can prevail- the Snowden revelations were a happy example. But many of even the revelations of journalism rest as much on power politics as they do on truth. Watergate wouldn't have mattered if there wasn't a sufficient consensus in Washington, among powerful people, that Nixon had gone too far. Equivalent scandals can evoke yawns without powerful backers, etc.
Now, go to the current election and you have a candidate of the corrupt permanent government against something like psychopathic candidate of a particular dubious right wing power complex; hardly inviting as a choice. How much are journalists "sacrificing their ethics" to push an arguably less evil? I assume quite a bit but how much should be concerned? I leave that question to you.
