That’s the whole point of “apps”. Apps are opinionated points of view / prisms over the network. Of course they’re able to apply their own moderation decisions. That’s how the whole mainstream web works in general — you can’t even get an unmoderated app into App Stores.

The difference is that it’s competitive. New apps can rise up that provide alternative lenses over the network. In the crudest case, literally showing everything. Which is what you wanted. Maybe that won’t get into an App Store but it definitely works if there’s demand for that.

That’s not really true. For one, you can have different AppViews which don’t do that. The feeds can be algorithmic however you the user want — multiple apps means you aren’t tied to what one central creator desires for those algorithms.
