In my opinion, the problem with Bluesky is that it assumes people want old Twitter/social media back. Beyond their protocols (which the vast majority of social media users do not care about), there is little innovation in the UX or platform. Old Twitter had its moment, and was relevant for a time. But the ship of the last 20ish years of social media has sailed, and people either want something new and different, or they’re ready for it to go away entirely.
