Your wish comes true, in 3 years activitypub is just another victim of EEE.

Granted. You no longer need to go to c/insanepeoplefacebook, it comes to you.

Wish granted. Never again shall children avoid their parents on social media by switching platforms, because now they’re all interoperable.

Granted. When a big sociat network publishes plans to integrate ActivityPub, many instances defederate it and those that don’t are blocked by the others, effectivaly making it a walled garden again.

…Oh wait…

Granted. There are now 15 competing standards to integrate activitypub, and they are not intercompatible

Granted. Effectively a ddos for all instances federated with Facebook. Only Facebook survives.
