I think when AT protocol is truly decentralised and there are many other clients other than Bluesky which is not controlled by AT protocol, then it makes more sense to support it. Because it started so closed up, it attracted a singular group of people and that culture became intense and extreme.
Given we have all been interacting with Jack's presence here closely, its easy to tell that he genuinely supports decentralised protocol and that he would likely fund innovations that is worthy beyond nostr, bluesky, web5 and more.
