I will probably switch to AT proto via Wafrn. (When I feel like getting around to do it.)
IMO AT proto is better protocol for web 3.0 social media than activity pub that feels like web 1.0 with interoperability.
AT proto is based on identities not on instances. If your instance is gone then too bad. Your account is gone too. In AT proto you can forcefully migrate your account.
Subscribing to independed labellers and feeds is also good. It feels like build your social media but with modularity than interconnected silos of instances.
I don't like that AT proto is controlled by bluesky but usefulness is better that principle. I will just switch to another thing when it enshittifies enough.
