“The term “engagement” is part of the familiar, sanitized language that hides how stupid a machine we have built. We must start using terms like “addiction” and “behavior modification.” Here’s another example of sanitized language: We still call the customers of social media companies “advertisers”—and, to be fair, many of them are. They want you to buy a particular brand of soap or something. But they might also be nasty, hidden creeps who want to undermine democracy. So I prefer to call this class of person a manipulator.”
