No because apps are decoupled many-to-many with hosting.

Every app can display public data from every other app because the source of truth is outside both apps (in hosting).

App owner can’t do bad things to your account other than banning you in their particular app. Other apps (even for same data) independently choose whether to show your data. So app owners are only in control over how your data is presented in their apps, not over your actual data.

Whereas in AP, each app’s moderators literally control your entire identity.
