It's likely just a selection process similar to politics. Are you willing to lie, mislead, deceive, and sell yourself to the highest bidder? No, well then good luck beating your opponent who is doing all that, going to have more funding, more widespread appeal, and never a single inconvenient position because his positions on everything are whatever polling tells him the voter wants to hear.
Newspapers (and employers in general) can now do similar filtering, if they want to, thanks to social media. If you're not committed to pushing a desired narrative, and willing to spin anything to fit it, then you're not getting hired. And given the state of society today, it's unclear if a newspaper with objective or diverse reporting would be able to compete against the current batch of confirmation bias delivery services.
