You fundamentally misunderstand how journalism works, then, and what is being lost in this shift.
In a newspaper there are two or three teams: news and/or opinion, and business. The teams do not tell each other what to do. Business doesn't tell news what to report on or how to write their stories. News doesn't tell opinion what to write or publish. And news doesn't tell business what ads are OK to run.
News and opinion take direct responsibility for what they publish. Every piece of content is put into the paper on purpose, usually written in-house. Their goal is to inform, enlighten, provoke, etc. -- to serve their society.
The job of the business team is to keep the lights on so more journalism can get done.
In a tech company like Facebook or YouTube, there are no such distinctions. Every decision, content or otherwise, is made for a business reason, and only for a business reason.
That's why YouTube and Facebook publish horrible, abusive, ugly content every day that no news or opinion editor would ever have cleared for publication. Facebook and YouTube don't care; they have no sense of a duty to society, and have no master other than the pageview, the click, the ad sale.
There are no "Chinese Walls" in modern ad-driven tech companies. It's worth remembering that those walls were built in journalism for a reason.
