Facebook isn't exactly a media company, but that's like saying the ocean isn't exactly a shipping company. Both of the former are essential ingredients to the free flow of the latter. Unlike the unsentimental ocean, though, Facebook is an entirely human construct, under human control, and rather than just carry news from publishers to readers, Facebook gets a say in how that news gets there. This matters especially when, say, employees of Facebook ask if their CEO can use the company to stop a presidential candidate from winning the office.

From Gizmodo:

Every week, Facebook employees vote in an internal poll on what they want to ask Zuckerberg in an upcoming Q&A session. A question from the March 4 poll was: "What responsibility does Facebook have to help prevent President Trump in 2017?" A screenshot of the poll, given to Gizmodo, shows the question as the fifth most popular.

It is, to continue the oceanic metaphor, as though the tides themselves wondered if they should sink a certain kind of ship, and then figured out how to do so. Facebook has over a billion users, and according to a Pew study in 2014, 64 percent of American adults use it.
