Right, that's exactly my point; Bluesky provides a centralized alternative to using your own domain name. (And moving from a did:plc to something decentralized is no easier than moving from mastodon.social or similar large instance to a smaller one!)

To be clear, I actually think it's a good idea to let people associate their own domains with their accounts, but I find it frustrating that people act like ATProto is the only or first example of open social protocols, as this TFA does.
