“Facebook, as well as Twitter and Google’s YouTube and the rest, have become the digital arms dealers of the modern age,” I wrote in one of my first columns after I joined the New York Times as a columnist in 2018. “They have mutated human communication, so that connecting people has too often become about pitting them against one another and turbocharged that discord to an unprecedented and damaging volume. They have weaponized the First Amendment. They have weaponized civic discourse. And they have weaponized, most of all, politics.”
