They are so insistent that most people want the entertainment use case for social media, they informed their protocol architecture design by that. No, no one wants that. Everyone is already sick of centralized social media services forcefully shoving recommended content from unknown people down their throats. They just want a chronological timeline of posts made by people they explicitly followed. No ads, no recommendations (Instagram's "mute recommended content for 30 days" is straight mockery btw), no prompts, no nothing, just updates from people you followed. And that's already solved by ActivityPub. Everything becomes much, much simpler when you don't need some kind of pool of "all posts in the universe" to choose from.
