Bluesky should stop pushing their own protocol and adopt ActivityPub and the Fediverse. They really don't offer anything that Mastodon or even Threads already have. It's another centralized mess in the making.
I'm a bsky fanboy normally but this is not a benefit. The functional part of bluesky is centralized. But they're open source and an open protocol so technically anyone can build a replacement
The intro explains some history and things which ppl here probably already know, but overall I find it provides a pretty good analysis of the current social media landscape, and these two protocols in particular.
