From a New York Times story by Benjamin Mullin and Mike Isaac headlined “Campbell Brown, Who Led Facebook News, Leaves Meta”:

When Facebook was being battered in 2017 for distributing false and misleading news, the social network turned to Campbell Brown, a veteran journalist, to smooth over its relationships with the media.

Six years later, Ms. Brown is departing the company, now known as Meta, as top executives have become less concerned about what the news media thinks about it.
