Are you serious? Y'all are so confused about what this is.
The entire point of services like Bluesky and Twitter is broadcasting your activity out to the internet for anyone to see (which of, course, is technically little-or-no different from "grab")
ATProto is not Bluesky, the later is just one app on the former. There are many more apps like Tangled, git on ATProto, which need private repositories.
You seem rather confused. I do not work for Bluesky. I am an independent developer building completely separate applications on ATProto.
Fair, I'm aware and I am conflating what people do with Bluesky and what ATProto can do. I absolutely do see the value in ATProto doing things that aren't "social media"
