This completely ignores the fact that - in the US at least - many newspapers started as organs of the local political parties. They always wanted to get their news out to their people. Then it went into full fledged "yellow journalism" that was all about the headline and engaging emotions vs objectivity.. which should sound familiar. And that was the late 1800s!
Around 50-60 years ago, as "mass market" became a thing and ad revenue exploded, newspapers and journalism as a whole veered towards objectivity because the local furniture store wanted to advertise to everyone not just one party. But if you read interviews, memoirs, notes, and the like of the journalists for that era, their stated goal for being a journalist was "to change the world." We can debate the specifics of what that means but it's not interchangeable with "neutral observer and reporter of facts."
Like many things, this appears to be a pendulum and it's swung from neutrality/objectivity back towards the opinion-based, light on facts approach for now.
How long we stay there and the consequences are yet to be determined..
