How much control does Jeff Bezos exert over the Washington Post?

I was interested in the Washington Post's oversight dynamic after reading more about Jeff Bezos and his decision to privatize the company. Publicly traded corporations in the media field often lay off reporters to increase profits to please their shareholders and answer to Wall Street, so I think that the independence of the media ownership in Jeff Bezos is really intriguing because the Post has shedded a group that other news outlets are still accountable to.

But how does the individual ownership influence media coverage by the Washington Post?

One of the most interesting aspects of investigating this question is the similarity of attacks by both Bernie Sanders and Donald Trump against the Washington Post's coverage of them individually.

In a speech last month in New Hampshire, Bernie Sanders attributes his unfavorable coverage in the Washington Post to his frequent attacks on Amazon's tax payments. CNN headlines the video "Bernie Sanders makes Trump-like attack on Washington Post" and features a response from Executive Director Marty Baron (who Bezos retained in the organization after his purchase) emphasizing the full independence that Bezos grants the Washington Post.

Similarly, the Washington Post finds itself a frequent scapegoat from President Trump for his negative coverage, with his frequent tweets deriding the "Amazon Washington Post". Given Trump's oversight of the FCC, his relationship with the media and specific media outlets can potentially have effects on far-reaching policies. But does he have any power to make moves against the Washington Post?

Another interesting part of this story is that outlets like Fortune have reported on the negative coverage of Amazon in the Washington Post as evidence that Jeff Bezos lacks control over the coverage of the Post.

What are the implications of privately owned media companies? Will there be similar criticism of Salesforce CEO Marc Benioff's purchase of TIME Magazine?
