It's difficult, we compare two different views, one from tech-perspective, and one from user-perspective.
I understand your arguments about the technology, they are absolutely correct, but they attract a typology of niche users, which are extremely demanding and very difficult to convert to paying users.
Twitter, the platform is very glitchy, the owners are who they are, the developer access is horrible, but still, I am using it, because there is exclusive and fresh content.
Bluesky is an interesting project, but I can strongly suggest leaning toward content/user-focus than pure-tech, in order to secure a stronger business-model (and eventually, as a consequence, a sustainable + open ecosystem).
Focus on onboarding great content first, and then walk back to the tech, not the other way around.
For example, to support more extensively those newspapers or institutions to onboard the platform, and most of all, all these unofficial content creators.
There are also some things which feel very strange, like the main description of Bluesky when you search for it on Google: "Simple HTML interfaces are possible, but that is not what this is".
