Obviously Tangled can live completely separate from Bluesky, it doesn't even need to share branding. Protocols are just protocols and people who don't understand how email works often don't even realize that Outlook and GMail use the same protocols. I'm hoping for this future personally where ATProto is only something the nerds care about (and write code for.)
(Please don't respond to this post with ideological argument. I'm just trying to talk about Bluesky and ATProto.)
