Maybe wasn't that way before, but when signing up on Bluesky now you are asked to choose a instance (bsky.social being the default), and the username contains the instance name, exactly like any Fediverse account.
I guess then a key difference is that Bluesky is presented to 𝕏 users as the same kind of monolith as 𝕏 whereas Mastodon is presented to them as a huge number of instances from which they absolutely have to pick one.

Good to know.
Strangely, people don't seem to mind.
