Facebook drew fire after actors linked to Russia ran thousands of ads on the platform in an effort to meddle in the 2016 presidential election.
The trending section has proved problematic in several important ways. First came a report that its human editors were biased against conservatives.
After Facebook fired those editors, the algorithms it replaced them with couldn’t always distinguish real news from fake.
In many ways, those issues foreshadowed Facebook’s more recent problems with fake news and political balance.
According to research from Pew, about 44 percent of U.S. adults get news from Facebook.
