To each their own. I prefer the centralized-yet-open approach of bluesky to the artistic chaos of mastodon. I like the idea of mastodon, and it's great for certain kind of people and certain kind of discussion, but I hope you agree that it will never be mass adopted.
It's possible that it will become mass adopted in the future on account of its (effective) uncensorability. The gulf between Bluesky and Mastodon UX is, in my opinion, relatively small and fixable with a bit of effort.
