Mosseri says the app finds the most success in blending entertainment with interacting with friends. That could look like commenting on a public post about a sporting event and interacting with a friend in the comments, he says. That’s important since Meta noted in documents around 2018 that people were sharing less in their feeds, and public content was increasing. The FTC is trying to point out that even if posting to the apps has declined, there’s still friends and family interaction happening.
