Removing the need for existing newspapers to rely on advertising to keep costs low enough for the consumer to be able to purchase an issue would go very far.
The problem has always been that the academic or “platonic” ideal of journalism as this “objective, 4th estate” that “speaks truth to power” has always been at odds with the costs of doing business. In fact, the first newspapers were owned by Political Parties and wore their affiliations on their sleeves. Switching to advertiser-supported models enabled more independence from political parties in the 1800s.
What’s also true is that most local newspapers (heck, papers in general) are at least on paper, objective in the sense that their journalists are free to pursue and write the stories they want using their professional judgment.
