It's interesting how much of social media's business model basically depends on forcible intermediation of personal relationships. Like, two friends might come up with the idea of a streak, or some competitive game or running joke. But as soon as the platform operator establishes this as a 'feature', they'are abrogating authority to themselves to decide how these personal interactions should be conducted, and it's clearly not for the benefit of the people involved.
I'm sure you understand the concept of platform operators having unilateral authority over what users do there.
