I am also, but maybe in a different way.
As someone who helped create ActivityPub and works every day to promote its use, I absolutely believe that everyone should make and use ActivityPub-native software. At SWF, we only do ActivityPub projects.
But if someone chooses to build on ATProto, and to make their software and accounts bridgeable so we can stay connected, that's infinitely better than being cut off entirely.
I mentioned elsewhere that I think supporting the openness of the Atmosphere is important for whatever comes next there. Whether BlueSky thrive or don't survive, the more the ATproto stack is standardized and independent, the better it is for the Fediverse.
